Wow. I hadn’t even heard of this until a few weeks ago, but apparently the top 5% finishers of every Tough Mudder event qualify for “The Toughest Mudder” competition at the end of the year.
From the Tough Mudder Website:
“World’s Toughest Mudder is the culminating event of the 2011 Tough Mudder Event Series, and will be a two-day challenge with one goal: to find the toughest man or woman on the planet. When the mud settles on December 18, one person will have bested over 150,000 Mudders for the right to call him or herself the World’s Toughest Mudder!”
Are you the World’s Toughest Mudder?
