I found this article and thought it was worthy to report here. This was originally posted on Livestrong and written by Pete Williams. This nicely recaps everything we have been saying on our show. You can find the full article here.
In the world of endurance sports, 2012 was the year of the obstacle race, with more than 2 million people competing in some sort of muddy challenge run.
Last year nearly 500,000 people completed a Tough Mudder, the 12-mile slog through strength challenges and Fear Factor-style obstacles, and just as many went through the shorter (5K) Warrior Dash. More than 350,000 competed in one of three versions of Spartan Race, ranging from 3 to 15 miles and requiring athletes to perform 30-burpee penalties each time they fail an obstacle, as well as navigate a gauntlet of mallet-wielding Spartan warriors to reach the finish line.
