In September 2012, I ran the Warrior Dash with my friend Allyson. It was 5k+ of running and lots of obstacles.
Some of the obstacles included: climbing over hurdles, climbing under barbed wire, running through tires, scaling a wall, crossing a balance beam, swimming across a lake, wading through knee deep water, climbing over a net, jumping over fire, crawling over logs in muddy water, etc.
It was a blast! The obstacles were fun and I had an awesome time with my friend.
I don’t think I got dirty enough, though…
