How can I become a better runner?
There are a few things you can do to become a better runner:

1. Train consistently - Endurance running creates physiological adaptations which take a long time for you to notice. Try to run at least 3 or 4 times a week for at least 30 minutes to begin building those adaptations. 
2. Get enough sleep - studies show that muscles recover better if you get at least 8 hours of sleep each night.
3. Fuel your body - you can't gain muscle if you don't provide your body with enough calories to keep yourself fueled. Ensure that you are eating a good mix of protein, carbohydrates, and vegetables to set yourself up for success.
4. Don't overtrain - One common mistake new runners make is to run more than they are trained to manage and end up injuring yourself. You can't build fitness if you are off of training due to injury!
