It's not just a mode, it's a way of life. A way of life that's fueled by coffee, sweat, and the occasional cry for help.

Here are some techniques that'll help you survive the never-ending torture of Marathon Mode:

1. Tunnel Vision - Focus on the next mile, then the next, then the next...

2. Caffeine Overload - Because who needs sleep, anyway?
3. Self-Torture - Find a new way to hurt yourself every 5k.
