This is good hack and I used a similar plan to travel 9 times this distance (240Km) in as many days ~ http://www.flickr.com/photos/bootload/collections/7215762379... the hack described will not work for completing consecutive marathon distances without some modifications.

My hack involved breaking the day down into "do-able" tasks, following some simple routines and good level of fitness to start with. You need to increase your level of basic physical fitness: cardiac (stamina to do the distance), joint & muscle (to avoid foot & muscle damage) and mind (won't quit).

Physical Prep: Before I started I'd marched some 1600km on foot slowly building up stamina so I could regularly do 32km per day for days in a row. I did this in hilly terrain with weights ~ http://www.flickr.com/photos/bootload/sets/72157623445003205... This is my hack to take this to another level. You have to be physically able to take the repeated distances and you can only do this with extra training to condition your muscles, joints and mind.

"1. # Don’t plan on running the whole thing"

The team was divided into 2 groups - runners, walkers. The runners would run anywhere from 13km to 20km in the morning and doing an additional 20 or so kilometers in the afternoon with a break for lunch ~ http://www.flickr.com/photos/bootload/4665359650/in/set-7215... Then completing the rest of the day together. I chose walking the entire distance not because I couldn't run the mornings but because I knew the chance of injury was pretty high. Instead we'd leave much earlier than the runners and beat them to the midday RV. Only 2/12 runners completed the distance because of injury.

"2. Take 4 Advil an hour before the race"

to blunt any residual soreness but the problem can also mask injury.

"3. Take a walking break at every mile marker"

we'd break for lunch but the more important break was stretching ~ http://www.flickr.com/photos/bootload/4665736877/in/set-7215... At the start of the day, at lunch and any time your calves would tighten I'd do 3 stretches of the calf, hamstring and quadriceps. In between we might depending on how we felt take a 5m timed break every 2 hours ~ http://www.flickr.com/photos/bootload/4665462901/in/set-7215... The longer or more often you stop, the longer it takes.

"4. Eat half a banana whenever you see one"

Eat small amounts regularly. Small amounts so you can digest it. If you fail to eat you will fatigue quicker and recover slower. Meal times was as many calories as possible. I'd also take left over food/drink to keep in case I got hungry. I used specialised rations (MRE/PRE ~ actually PR1M ~ similar to this Australian D ration "click Austalian" to view ~ http://www.nytimes.com/interactive/2010/09/04/weekinreview/2...) when we got into the heavy climbing sections ~ http://www.flickr.com/photos/bootload/4549780731/

"5. Take two waters at ever water station"

Carry you own water. Drink on average (varies by climate) 1-2Ltr/hr and verify this with the "piss-test" - if your urine is clear you are drinking enough. We had 50litres of water on hand and various additives to replace minerals.

"6. Eat no more than 3 Gu energy packs because our stomachs didn’t like them"

Small amounts at regular intervals to avoid such stomach aches. I made up some homemade "rat-packs" ~ http://www.flickr.com/photos/bootload/4549780725/ to eat at regular intervals to make sure I had enough energy.

"7. Take bathroom breaks."

Never forget doing a #2 under a bridge only to find a live electric fence very close.

"8. Walk every hill"

We actually tried to push hard up hills because the country was undulating but other times the hills stretched up to 15km up so there was no choice. Hills add about 1hr for every change of 1000ft so moving fast down also helped.

"9. Meet interesting people and use conversation to kill the pain"

That works but sometimes you can be on your own. On the second last day we traveled > 40km mostly uphill without a stop and most of that was by myself. You've got to like the pain.

"10. Put bandaids on your nipples to prevent bleeding"

Foot care is more important. An old rule is never wear anything new so all my kit was broken in, boots ~ http://www.flickr.com/photos/bootload/4418965410/in/set-7215... pack etc. At all main stops taking your boots off & letting your feet & socks dry in the sun avoids this type of problem ~ http://www.flickr.com/photos/bootload/4413036580/in/set-7215... This is what happens if you dont ~ http://www.flickr.com/photos/bootload/4998112005/in/set-7215...

11. We kept going until end of distance

While we had a van for stragglers or injured we had to finish the days course on the day.
This turned out to be the hardest aspect. Finishing. You can see it in this shot, shattered legs ~ http://www.flickr.com/photos/bootload/4666299830/in/set-7215...
