Ah Colorado. This was the 3rd year that spartan has done the military sprint at Fort Carson Army base. For those of you who would like a challenge with the spartan sprints, seriously look at this race. The obstacles are dense. In 4.5 miles we completed 25 obstacles. Sometimes back to back, and at the finish there are spear, Hercules hoist, dunk wall mud climb,slippery wall, horizontal cargo net bridge, fire jump and gauntlet.
