# A Comprehensive Guide to Running

Just because you can run, it doesn't mean that you know how to do it properly.

This [systematic review](https://www.sciencedirect.com/science/article/pii/S2095254621000454) showed that:

> 50% of runners experience an injury each year that prevents them from running for a period of time, and 25% of runners are injured at any given time.
> 
> Running-related musculoskeletal injuries (RRMIs) are common among runners. These RRMIs are usually caused by the application of relatively small loads over many repetitive cycles.

When your form is wrong, because running is a repetitive motion, you are compounding the same mistake over and over—a surefire way to get injured. So it’s important to not assume that you know what you’re doing. **Running is more complicated than it looks.**

* * *

I’ve been running for over a decade, and I’ve made almost every mistake possible. **I put together this comprehensive guide to help both beginners and experienced runners alike.** The sections are presented in descending order of importance (starting with the most important topic: injury prevention).

Once you understand the basics of running, it’s a fun sport/hobby to do by yourself or with friends, the [runner’s high](https://www.google.com/search?q=runner%27s+high&rlz=1C1CHBF_enUS924US924&oq=runner%27s+high&gs_lcrp=EgZjaHJvbWUyDAgAEEUYORixAxiABDIKCAEQABixAxiABDIKCAIQABixAxiABDIHCAMQABiABDIHCAQQABiABDIHCAUQABiABDIHCAYQABiABDIHCAcQABiABDIHCAgQABiABDIHCAkQABiABNIBCDE4NzlqMGo3qAIAsAIA&sourceid=chrome&ie=UTF-8) feels good, there’s a sense of accomplishment from getting faster, the aerobic exercise gives you energy throughout the day, and you sleep better at night.

Now let’s get started with the most important topic of all.  
 

**1\. Injury Prevention**
=========================

**(A) Good Running Technique**
------------------------------

A physical therapist once told me that **good running form is essentially “controlled falling.” **You can try the following right now: stand up straight and begin leaning forward while bending at your ankles (like Michael Jackson in the song Smooth Criminal). Keep leaning forward until you’re forced to take a step to stop yourself from falling onto the ground. Did you notice which part of your foot you landed on?

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/d66228fce293ca850fed9f0499c678ab7b943585bd80cbc8.jpg)

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/615eea53080af734137da6758ea715e2469b4ba937d15842.jpg)

You probably landed on your midfoot (and not on your heels or on your forefoot/toes). (Note: this demo works better when you’re wearing shoes).  
 

### **(i) Midfoot Striking**

**Your midfoot is where you want to land with each step while running. **Many people run by landing on their heels (known as “heel striking”) too far in front of their bodies (known as "overstriding")—don’t do this! [Experienced runners know that](https://www.coreadvantage.com.au/blog/the-problems-with-a-heel-strike#:~:text=Is%20Heel%20Striking%20Bad%20When,stress%20fractures%2C%20and%20runner's%20knee.):

> Striking the ground on your heel and in front of the body is essentially creating a braking force, sending you backward. When you heel strike, you put excessive stress on your lower legs and knees, increasing the risk of injuries such as shin splints, stress fractures, and runner's knee.

Landing on your midfoot improves running efficiency, and more importantly, mitigates injury risk compared to heel striking.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/4c8ddfd792c48ec34cad373b76b9ed9c0fd00626dd6a5b27.jpg)

So how do you avoid heel striking and learn how to land on the midfoot?  
 

### **(ii) A 10-16° Forward Lean**

**To avoid heel striking, lean forward more by bending at the ankles** (like Michael Jackson), but do not bend at the waist. A 10-16° angle is optimal for a forward lean. Your head, shoulders, waist, and ankle should be in a straight line.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/54b061d46e1faa23bc6a48388f93650f05a41290e85b9f55.webp)

Running upright, with a 0° forward lean, increases the likelihood of heel striking. And with a forward lean greater than 16°, you might tumble forward onto the ground—ouch. (By the way, Michael Jackson was only able to do a 45° lean because of a [clever illusion](https://www.the-independent.com/arts-entertainment/music/news/michael-jackson-smooth-criminal-45-degree-forward-tilt-illusion-a8363946.html#:~:text=%22MJ%20pulled%20off%20a%20gravity,gravity%20muscles%2C%22%20they%20wrote.&text=Sign%20up%20now%20for%20a,Terms%20apply.&text=with%20Amazon%20Music-,Sign%20up%20now%20for%20a%2030%2Dday%20free%20trial.,turn%20faster%20than%20ever%20before.%22)).

**Still unsure on whether you’re heel striking?** Try the following. Run upright and really exaggerate a prominent heel strike (by flexing your toes back). Then slowly lean forward at the ankles as you run. As you keep leaning forward more and more, you’ll notice that it’s impossible to land on your heels. Finally, maintain that forward lean and stop tensing your feet. This is what landing on your midfoot should feel like.  
 

### **(iii) Arms**

Pumping your arms harder will not make you faster (unless you’re doing an all-out sprint). Your overall speed comes from your legs, not your arms. The arms are there just to keep you balanced.

**Keep your arms bent at a 90° angle, with your fingers curled as if you’re loosely holding an imaginary egg. **While you run, your hands should cross your body slightly, but they shouldn’t cross the nipple on the opposite side of your body.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/88cc18705460e16c25f2e1534dde6e9ed30b7162fb332dc3.png)

* * *

I’ve covered (1) midfoot striking, (2) the forward lean, and (3) arms—the three pillars of good form. Now let’s turn to another aspect of injury prevention: a structured running plan.  
 

**(B) Training Structure**
--------------------------

Even though you know good running form now, you can still get injured if you don’t understand the basics of a weekly training structure.  
 

### **(i) Zone Training**

**You should not perform every run at the same intensity. **Instead, you should vary your runs according to different heart rate zones.

These zones can either be (1) *calculated *based on percentages of your maximum heart rate, or (2) you can estimate them based on *vibes*.

(1) **Calculation**:

*   220 - (your age) = MHR (maximum heart rate, which is measured in beats per minute (BPM)).
*   So for me that’s 220 - 26 = 194 BPM, which I sometimes achieve when doing an all-out sprint.
*   The five heart rate zones are then calculated based on a percentage of your maximum heart rate. So for me:
    *   **Zone 1** is 50-60% of my MHR, or 94-114 BPM
    *   **Zone 2** is 60-70% of my MHR, or 114-134 BPM
    *   **Zone 3** is 70-80% of my MHR, or 134-154 BPM
    *   **Zone 4** is 80-90% of my MHR, or 154-174 BPM
    *   **Zone 5** is 90-100% of my MHR, or 174-194 BPM  
         

GPS watches are great because they can track which heart rate zone you’re running in:

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/b8585f799db25cdb0692b3f8fe1978e23e2c19af9986af56.png)

*This person is running in Zone 3 according to their watch.*

If you plan to train in Zone 2 for the day, periodically look at your watch and adjust your speed. → Heart rate in Zone 3-5? Slow down. Only in Zone 1? Pick up the pace.

After your workout, these watches show the time spent in each zone:

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/76d59b7876dca2f1bb09d0d94054d404c1769a34547be30d.jpg)

*This morning I ran 34 minutes in Zone 2, and a few minutes in Zone 3.*

(2) **Vibes**:

*   If you don’t want to run with a watch or phone, here’s what the heart rate zones feel like based on vibes:
    *   **Zone 1 **— Can talk for hours with no problem.
    *   **Zone 2 **— Can maintain a conversation, but only a few sentences at a time. You’re on the edge between breathing through your nose and having to breathe through your mouth.
        *   Everyone’s Zone 2 is different depending on their cardiovascular fitness.
            *   A new runner may be in Zone 2 while running at a 14 minute/mile pace.
            *   My friend in Chicago who runs 80 miles/week is in Zone 2 while running at a 7 minute/mile pace. His body’s cardiovascular system has become incredibly efficient after years of training. So for him, a 7 minute/mile pace feels like a light jog, but it might feel like an all-out sprint to somebody new to running.
    *   **Zone 3** — Can only exchange one sentence at a time. Breathing has become more labored and is now fully through the mouth.
    *   **Zone 4** — Can only say a word or two before taking several breaths. This should feel comfortably difficult, but not an all-out sprint.
        *   Colloquially it’s known as a “tempo run” if you stay in Zone 4 for the duration of a run.
    *   **Zone 5** — No conversation possible.
        *   This is only achieved during speed workouts or a race.

These training zones are useful if your goal is to get faster (or just not injured). You should use them in combination with the **80/20 Principle**.  
 

### **(ii) The 80/20 Principle**

Imagine going to a gym and attempting your maximum bench press, then coming back the next day to attempt your maximum bench press again, and doing it the next day, and the next…This is stupid. Your body needs time to rest. You will get injured doing this.

The same thing applies to running. **Performing every run, day after day, at a high intensity is asking for trouble. **And trouble is what I got. The #1 mistake I made for years (which led to many avoidable injuries) was performing all my runs at the same high intensity.

So how do you avoid this and not get injured?  
 

**80% of runs should be performed at Zone 2. These easy runs help the body recover from the 20% of runs you perform at Zone 4 or Zone 5.**  
 

This is what my running schedule looks like:

*   Monday — Speed workout on a track, consisting of 400m and 800m reps performed at Zone 4-5, with 3 minutes of rest between reps
*   Tuesday — Rest day (no run)
*   Wednesday — Zone 2 run
*   Thursday — Zone 2 run
*   Friday — Tempo run (a Zone 4 run)
*   Saturday — Zone 2 run
*   Sunday — Zone 2 run

Four of my six runs are at Zone 2—that’s only 66% and not 80%. But take a look at my total time spent running:

*   My four Zone 2 runs are ~25 minutes each for a total of 100 minutes.
*   My Zone 4 tempo run is only ~20 minutes.
*   My Zone 4-5 speed workout is cumulatively ~10 minutes (not counting the time spent resting).

So 100 of my 130 minutes spent running each week is in Zone 2, which is close to 80%. **The 80/20 Principle for zone training is about the quantity of time, not the number of sessions, spent in each zone.**

I stopped getting injured when I started following the 80/20 Principle of training, especially once I combined it with the 10% Rule.  
 

### **(iii) The 10% Rule**

If you run your first ever mile today, can you run a marathon tomorrow? No. You’ll probably get injured attempting a marathon. Your body isn’t accustomed to that level of exertion. If you don’t want to get injured, follow the 10% Rule.

**The 10% Rule**: Only increase the distance ***or*** the speed of your runs by at most 10% each week. Don’t increase both in the same week.

**Mileage**:

Let’s say this is your current running schedule:

*   Two miles, 4x/week at Zone 2, at a 12 minute/mile pace.
*   One mile, 1x/week at Zone 4-5, at an 8 minute/mile pace.

Your total mileage is 9 miles/week. Increasing to 10 miles is roughly a 10% increase. Per the 10% Rule, if you increase your mileage in a week, do not also increase your speed that week.

Note: if you’re running 3x/week and want to start running 4x/week, make sure your total mileage for the week doesn’t jump more than 10%.

**Speed**:

Using the same setup as before:

*   Two miles, 4x/week at Zone 2, at a 12 minute/mile pace.
*   One mile, 1x/week at Zone 4-5, at an 8 minute/mile pace.

Instead of increasing your mileage, you could focus on getting faster. For example, try performing your Zone 2 runs at an 11:45 minute/mile pace. If that pace is too fast and pushes you out of Zone 2 and just barely into Zone 3, that’s okay. Do that faster pace for a week, and as your cardiovascular health improves, that new pace will become Zone 2 for you.

Alternatively, you could focus on increasing the pace of your Zone 4-5 run for a particular week.

* * *

**By following the 10% Rule, you gradually build your muscles and endurance without overwhelming your body with too much running.**  
 

### **(iv) Where to Start if You’re a Beginner**

The 10% Rule is meant to prevent you from doing too much. But how much running should you start with per week if you’re a beginner?

I haven’t found a good answer on the internet. Most sources say you’ll be fine if you **start by running 10-20 minutes, 3x/week.**

I would suggest trying to find your Zone 2 pace and your Zone 4 pace, then start building a training plan (using the 80/20 Principle and the 10% Rule) based on your current level of fitness.  
 

**(C) Change Shoes Every 250-350 miles**
----------------------------------------

Let’s assume you’ve been running pain-free for the last six months. Your form is good, you follow the 80/20 Principle, and adhere to the 10% Rule. But suddenly, you’re starting to experience consistent knee pain, or shin splints, or some other pain on your runs. This could indicate that your shoes are worn out.

**Modern running shoes only last 250-350 miles.** After that, their tread gets worn out and they lose their cushioning.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/7ed845882ecf536f15a9dccb043c4754da6b68835edef7ff.jpg)

*Left: a brand new shoe. Right: the same shoe after 6 months of running. *  
*See this article: *[*6 Signs It’s Time to Replace Your Running Shoes*](https://runningstate.com/when-to-replace-running-shoes/)

Don’t feel like tracking your accumulated mileage by hand? Consider using the [Strava app](http://strava.com). It can track the number of miles you’ve used a pair of shoes for, and send you an alert once you’ve reached 250-350 miles. Once you have, throw them out and buy new shoes.

For all other aches and pains…  
 

**(D) Hire a Coach or Visit a Physical Therapist**
--------------------------------------------------

They’re experts. They’re effective. And they’re inexpensive—about $50-100/session.

In my experience, **visiting an expert has an extremely high ROI.** They can help finetune any running form problems, or provide rehab exercises to help you recover from an injury.  
 

### **(i) What to Do if You’re Injured**

After a decade of running, I tacitly know the difference between discomfort from normal exertion, versus pain that could be indicative of an injury. For beginners, that can be difficult to recognize. So what’s a good benchmark to use?

**If your pain is more than a 5 on a scale of 1-10, stop running for the day.** If the pain persists for multiple days in a row—you’re probably injured. 

Follow the saying: ***when in doubt, get it checked out.*** A running professional can diagnose you and provide rehab. Or you can just wait a few days, or weeks, to see if it gets better on its own.

Note: **any aches or pains felt for the first half mile of running can sometimes resolve themselves if you just keep going as your body warms up.** But after a half mile, if something still doesn’t feel good, stop for the day. Your body has likely not fully recovered from previous runs.

For the love of god, just don’t push through the pain thinking you’re a badass. You’ll just fuck yourself up even more. If you’re in pain, stop running.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/a1b90acb64f1de587b67e1b20d119f19a3aef6cb0b696d59.png)

If you’re injured and still want to do cardio, **consider cross-training**. Other sportslike cycling, swimming, elliptical, etc., can also be performed with 80/20 Zone training to improve your cardio. Just make sure they don’t exacerbate the pain in any way.  
 

**(E) Runner’s Stitch**
-----------------------

While running, if you’ve ever felt a sharp pain in your abdomen (under your ribs on the left or right side), this is not an injury. This is called a **runner’s stitch**.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/045a9ccff4bf61e854431a310c9e173af90866a9639db20c.jpg)

In my experience, **runner’s stitches happen when I’m not adequately prepared in terms of my nutrition or hydration **(the topics I’ll cover in the next section). 

If you’re experiencing a runner’s stitch during a run, **there is a remedy**:

> Let’s say the stitch is on your right side. Breathe in through your nose while landing on your right foot, and breathe out *hard* through your mouth and stomp on your left foot while continuing to run. Heads-up: this is going to suck. But after 30-60 seconds the stitch should go away. Then you can resume running normally.
> 
> Yes, it is possible (but rare) to have a runner’s stitch on both sides. The same remedy applies—you’ll just have to do one side for 30-60 seconds until it’s resolved, and then the other side.

Again, with proper nutrition and hydration, you probably won’t experience this pain during your runs.  
 

**2\. Nutrition/Hydration**
===========================

**Avoid eating 1 hour within a run. **Doing so increases the likelihood of an upset stomach or a runner’s stitch. If you run first thing in the morning, fasted cardio is 100% okay to do—that’s how I do most of my runs.

**Avoid drinking lots of water right before a run** for the same reason. 

I normally wake up, drink a little water, go for a run, and then eat breakfast.  
 

**(A) Nutrition**
-----------------

Simple rule: eat like shit, gonna run like shit. 

A few months ago, I binged on pizza and beer at a party on a Saturday night. The next morning I went for a run and almost shit my pants.

**Try to eat mostly whole foods **(as opposed to processed/junk food). I’ve eaten the same breakfast/lunch/dinner every day for 3 years (which I wrote about [here](https://www.lesswrong.com/posts/iDswXwviMRAfT6rB5/5-000-calories-of-peanut-butter-every-week-for-3-years)). It works for me.  
 

**(B) Hydration**
-----------------

**You’ll know if you’re hydrated depending on the color of your pee.**

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/9701bd5b36eb15a469d42f305a2e90d592a4ff13225359db.jpg)

Dehydration can lead to worse performance and sometimes a runner’s stitch. Overhydration is also unpleasant (because there’s an uncomfortable pressure of needing to pee).  
 

### **(i) Are Electrolytes Necessary?**

Electrolytes are minerals that restore your energy levels. They can be obtained via beverages (like Gatorade or LMNT), or through a healthy diet.

**Are sports drinks with electrolytes mandatory? No. **I just eat my normal meals after a run and feel fine.

It’s only at the elite levels of running, or marathons, when you need to start meticulously tracking your energy levels.  
 

**3\. Should I Warm-Up?**
=========================

**The purpose of warming up is to decrease stiffness and increase performance.** Warming up consists of slowly running a short distance of 0.25-0.5 miles (typically done at Zone 1-2), and then doing some dynamic stretches.

**Is warming-up always necessary? Eh, usually not.** For the bulk of your runs performed at Zone 2, you don’t need to warm-up. The only time I warm-up is before speed workouts and races.

After running a slow half mile, here are my warm-up exercises (which altogether only take ~5 minutes to do):

*   [Toe walks](https://www.youtube.com/watch?v=3d2S7a3D9YY&pp=ygUJdG9lIHdhbGtz)
*   [Heel walks](https://www.youtube.com/watch?v=aZ15aYKjx58&pp=ygUKaGVlbCB3YWxrc9IHCQmtCQGHKiGM7w%3D%3D)
*   [A-skips](https://www.youtube.com/watch?v=A7r6yCpmSrA&pp=ygUHYSBza2lwcw%3D%3D)
*   [B-skips](https://www.youtube.com/watch?v=A7r6yCpmSrA&pp=ygUHYSBza2lwcw%3D%3D)
*   [Hip openers](https://www.youtube.com/shorts/Odx8JXVNBdI) (done forwards and backwards)
*   [High knees](https://www.youtube.com/watch?v=N4VwL0WGhzw&pp=ygUKaGlnaCBrbmVlc9IHCQmtCQGHKiGM7w%3D%3D)
*   [Up & unders](https://www.youtube.com/watch?v=xRjl6d9mtCo&pp=ygUMYnV0dCBraWNrZXJz)
*   [Karaoke](https://www.youtube.com/watch?v=94ixIbZPrHc&pp=ygUPa2FyYW9rZSBydW5uaW5n)  
     

**4\. Gear**
============

Don’t spend too much. Running is an inexpensive sport/hobby.  
 

**(A) Shoes**
-------------

There are two basic types of shoes, each cost ~$100:

*   **Trainers**—higher in cushion and protect your legs from the high impact of running. They’re the shoe of choice for all of your Zone 2 training.
*   **Racing flats**—more lightweight than trainers because they have less cushioning. They’re your shoe of choice for speed workouts, tempo runs, and races.

**Racing flats are not required.** For my first 9 years of running, I only used trainers ([this brand](https://www.asics.com/us/en-us/gt-2000/c/aa50109200/), specifically). It’s only this past year that I bought my first pair of racing flats. Why? Because I’m getting a lot faster—a few less ounces of weight in my shoes makes a difference in performance for me.

As previously mentioned, I use the [Strava app](http://strava.com) to tell me when I’ve run 250-350 miles in a pair of shoes. Then I replace them.  
 

**(B) Clothes**
---------------

*   Athletic socks
*   Athletic shorts/pants
    *   [How long should your shorts be?](https://www.reddit.com/r/AdvancedRunning/comments/hx2ns3/should_length_of_shorts_male_be_tied_to_current/) (← sarcastic replies😉)
*   For shirts and underwear:
    *   Cotton is fine, but it absorbs sweat and can make you feel heavier
    *   “Wick-away” polyester/nylon materials absorb less sweat
*   Hat and sunglasses are good
    *   For speed workouts and races, I recommend removing your hat [because](https://runningmagazine.ca/sections/training/does-running-in-a-hat-make-you-slower/):
        *   "Wearing \[a hat\] during a race can actually increase your body temperature slightly, which could, in turn, elevate your heart rate. According to a [2019 military study](https://mmrjournal.biomedcentral.com/articles/10.1186/s40779-019-0208-7), wearing a hat during exercise can increase your body temperature by up to four per cent."  
             

**(C) GPS Watch**
-----------------

**Virtually everyone in my run club uses GPS running watches.** They can show your mile pace, what heart rate zone you’re in, and log your runs.

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/a0087186203a4f76f05aba43631cb42ed001b8baec844e28.jpg)

I bought my first GPS watch—a [Garmin 245](https://www.garmin.com/en-US/p/628939/pn/010-02120-00/)—two years ago. It’s lightweight and more convenient than holding my phone. A little expensive at $200, but **a game changer in terms of performance and data tracking.**

I’m biased towards the watch because it’s awesome, but I also did my first 8 years of running with just my phone. If you get serious about running, consider buying a GPS running watch.  
 

**5\. How to Get Faster**
=========================

If you just want to putter along at Zone 2 or Zone 3 a few times per week and don’t care about getting faster, have fun!

![](https://39669.cdn.cke-cs.com/rQvD3VnunXZu34m86e5f/images/0ac4ed269f22f0b2c7ce1cb83d5e0a3cab342342b34b8456.jpg)

If you want to get faster (and keep increasing your cardiovascular health in the process), here’s how:

1.  One speed workout per week
2.  One tempo run per week
3.  Lose weight
4.  Lift weights at a gym
5.  Note that temperature affects your performance

**If you choose to do only one of these, do a speed workout.**  
 

**(A) Speed Workout**
---------------------

To increase your maximum speed, **1x/week do a speed workout. **This can be performed at a high school or college track, or a park, or anywhere where your path is not obstructed.

**A speed workout is performed by repeating short intervals at a challenging, fast pace** (often at or above your 5K race pace).

A simple version could be to run 400m at Zone 4-5. Do that for 4 to 8 reps total, taking 3 minutes to rest in between reps.

Note: after finishing a speed workout, do not sit down or bend over. You’ll probably cramp up. Instead, keep walking around for a few minutes.

Do a speed workout 1x/week, and the rest of your runs at Zone 2. You’ll start getting faster.

If you want to get even faster, read on.  
 

**(B) Tempo Run**
-----------------

To increase your endurance, **include a tempo run 1x/week. **This should be in addition to your speed workout, not as a replacement, because the speed workouts will yield the most improvements.

**The tempo run is a sustained run at Zone 4** (about 20-30 seconds slower per mile than your 5K race pace). It should feel challenging, but it shouldn’t dip into Zone 5.  
 

### **(i) What’s the Difference Between Speed Workouts and Tempo Runs?**

*   **Speed workouts **help you get faster by strengthening your leg muscles, therefore increasing your top-end speed.
*   During intense exercise, lactic acid builds up in your muscles and causes fatigue. **Tempo runs** increase your endurance by improving your body’s ability to clear lactic acid, therefore delaying fatigue and helping you run faster for longer.  
     

**(C) Lose Weight**
-------------------

From author Matt Fitzgerald’s excellent book [*Racing Weight: How to Get Lean for Peak Performance*](https://www.amazon.com/Racing-Weight-Lean-Peak-Performance/dp/1934030996):

> A 160lbs runner expends 6.5% more energy than a 150lbs runner at the same pace.

Body fat and muscle tissue compete with each other for energy in the form of oxygen and fuel (glucose). **With less body fat, more energy will be directed to your muscles.**

For serious runners, this is an excellent book. It goes into detail on how to actually achieve fat loss.  
 

**(D) Lift Weights at a Gym**
-----------------------------

**Lifting weights accomplishes three big goals for runners **[according](https://www.runnersworld.com/training/a20074772/strength-training-for-runners/) to Jason Fitzgerald (a USATF-certified running coach):

1.  **It prevents injuries** by strengthening muscles and connective tissues.
2.  **It helps you run faster** by improving neuromuscular coordination and power.
3.  **It improves running economy**, which is how efficiently a runner uses oxygen to sustain a given pace, by encouraging coordination and stride efficiency.

  
Here, we diverge into two paths, depending on if you’ve lifted before:  
 

### **(i) You’re an Experienced Lifter**

If you’re confident in your lifting abilities, then go do some lower and upper body days in a gym once or twice per week.  
 

### **(ii) You’ve Never Been to a Gym Before**

If you’re curious about lifting and don’t want to get injured, I recommend one of two options:

1.  **Hire a personal trainer for a few sessions.**
    1.  It’s critical that your form is good while lifting weights, otherwise you could get injured. A personal trainer will set you up for success and teach you all the basics.
2.  **Ask a friend (who is an experienced lifter) for help.**
    1.  One time a friend asked me to help her learn how to lift—I dropped everything in my life to bestow upon her all of my gym knowledge. I’m talking lifting technique, different exercises, hypertrophy knowledge, optimizing sleep and recovery—the whole gambit. She lost 5lbs of fat in two months and gained some muscle.

If you’re ever not feeling confident about performing a particular exercise, search “How to do \[XYZ\] exercise” on YouTube. I recommend [Scott Herman](https://www.youtube.com/@ScottHermanFitness/videos). He’s an OG fitness creator who’s posted tons of simple 1-minute videos on how to perform nearly every exercise in the gym.

Note: gym people are often friendly and will help you if you have questions. If you ask someone for help and they’re a dick, ask someone else. If I was there, I would be happy to help you. 🙂  
 

### **(iii) Can You Gain Too Much Muscle?**

Increasing your overall muscle will help you become a more robust and faster runner…to a point. **Bodybuilders with tons of extra muscle, just like people with excess fat, are also slowed down by gravity.** If you want to run faster but you look like Arnold Schwarzenegger, consider losing some muscle.

Note: there is a difference in optimal body size depending on which running discipline you choose. Sprinters need more muscle to generate explosive force, whereas marathoners need to be as light weight as possible. Again, Matt Fitzgerald’s book [*Racing Weight: How to Get Lean for Peak Performance*](https://www.amazon.com/Racing-Weight-Lean-Peak-Performance/dp/1934030996) is an excellent guide for finding your optimal running weight.

Generally, weight lifting has helped me run faster for longer. Worth it.  
 

**(E) Temperature Affects Your Performance**
--------------------------------------------

[**50-60°F is optimal running weather.**](https://www.runnersworld.com/uk/training/a775069/what-hot-temperatures-can-do-to-your-running-and-how-to-cope/) Any warmer than this, and your body will be forced to divert energy to cooling you down, instead of using that energy to run faster.

If your Zone 2 pace at 60°F is 9:00 minutes/mile, at 85°F your Zone 2 pace may be closer to 10:00 minutes/mile. This is why I prefer to run in the morning.  
 

**6\. Sign up for a Race! Join a Run Club!**
============================================

**(A) Races**
-------------

Once you’ve been running for a few months, **consider signing up for a race—they’re fun! **They’re an opportunity to test your limits and beat your personal record (PR).

Races are cheap. The simplest one is the 5K race (~3.1 miles) and usually costs ~$30-60. Marathons are more expensive at ~$100-300.

Here’s some advice from a veteran runner (me): **don’t go out too fast. **Most beginners make this mistake. If you plan to run your 5K at a consistent 8 minute/mile pace, when the starting gun sounds, don’t blaze out of the gate at a 6 minute/mile pace—you’ll drastically slow down from fatigue a mile or two into the race.

**Want to perform well? Run negative splits. **This means each mile should be progressively run faster. So your first mile could be run in 8:05 minutes, your second mile in 8:00 minutes, and your final mile in 7:55 minutes.

Post-race refreshments are free and usually include bananas, water, sports drinks, donuts, and more. Dig in, you earned it.

**Overall, races are super fun, and runners are a supportive community. Highly recommend.**

*Here’s me at a recent Halloween run.*

**(B) Run Clubs**
-----------------

**Live in a major city? You probably have an active run club in your area.** Check for them on social media.

They’re free, filled with supportive/chill people who are into fitness, and it’s a good community (I’ve made friends through my run club; other people use them for dating).
