The 100!

The athletes at cfjax.com did a hefty version of this workout:

For time:
100m Farmers Walk  / Waiters Walk
100m Lunge
100m Sprint
100m Farmers Walk / Waiters Walk
100m Lunge
100m Sprint
100 Situps

Farmers / Waiters Walk:
So, in one hand at your side is your kettlebell (1.5 pood / 1 pood) and the other hand is holding a bumper plate overhead (25# / 10#).

My friend Ben showed me this link recently. The Toughmudder claims to be the toughest one day endurance event on earth, and it looks to be true. Sweet!
