My neighbor and I (I'm wearing the bandana) participated in the Tough Mudder event on July 14th 2012 on Mt. Snow, Vermont. It's a 10+ mile run and hike up and down the mountain with 25+ obstacles scattered along the trail. The course was designed for training by British Special Forces and includes lots of uphill and downhill, rocky trails, mud, water, ice, ropes, walls, crawling, climbing, barbed wire, and electrical wires!
This video was originally created by my neighbor's daughter (she also captured the footage) but I added the captions, replaced copyrighted music, and removed names to protect the innocent!
