Extreme Endurance Programs On the Rise Among Urbanites

Obstacle courses with a military training spin have many buttoned down, white-collar individuals crawling down in the mud and standing on each other’s shoulders during the weekends. There are a few different extreme endurance contests including Warrior Dash, Tough Mudder, and Spartan Race. Tough Mudder is the biggest, holding 35 races during 2012 in 4 countries with a total of around 660 thousand people participating.
