Tough Mudder race at Squaw
Tough Mudder participants take off from the starting line up a steep, slippery slope at Squaw Valley USA.
Tough Mudder hosts events all over the country and the Tough Mudder pledge explains that they shouldn't be considered races — helping other Mudders complete the course is more important than personal time.
The NorCal event (which took place Saturday and Sunday) featured a couple dozen obstacles across 12 miles of up and downhill terrain, and about 16,000 people competed during the weekend.
