One of the best ultra runners in the world, David Goggins is a machine. This Navy SEAL gets up and runs 10-15 miles in the morning before breakfast and then bike 50 miles round trip to work.
What's his motivation? To raise money for Special Operation Warrior Foundation which provides full college scholorships for kids of Spec Ops soldiers KIA.
And this guy doesn't even like running! Truly inspirational.
