One Heavy Mile (OHM) is the ultimate test of running-specific speed, strength, and endurance. The mile distance is perfect for testing leg speed and aerobic capacity, while the addition of heavy weight tests runners' power and muscular endurance. So, what exactly is it?
Quite simply, One Heavy Mile is a mile run while carrying something heavy. Most athletes choose to wear a weight vest or ruck, but you can do whatever you want. There are minimum weight requirements for certain award categories, but the idea is simple: run one heavy mile.
