Various Places– This odd race takes place in different cities all over the world, including races coming up in Las Vegas, London, and Chicago. During the race expect to get dirty in this team oriented race that makes you compete in a crazy obstacle course over 10-12 miles long. At the end of it, you’ll probably have mud in places no one wants to know about. Luckily though, it’s not a timed race and the creators like to state that it’s more about camaraderie over sport in the end.
