If you are the active outdoorsy type, then you can’t claim your full “active outdoorsy” street cred until you’ve completed one of these crazy marathons. Don’t worry – you have plenty of options. There’s the Warrior DashTough Mudder (which makes me think of Jayne from Firefly, just sayin’), Mud Ninja, and the Spartan Race among others.

These marathons have several common denominators. For starters, most all of them take place in forested areas and involve varying amounts of mud. Many obstacles include barbed wire and, in some cases, fire. At the end of your run, you are usually given something healthy to eat (for instance, a banana) and something unhealthy and edgy to drink (for instance, a beer). You also receive some type of cute/funny novelty that you can wear and makes the fact that you just contracted tetanus by wading through a filthy pond totally worth it.

The funniest thing about these races is the participants. They’re so psyched before the event, and afterwards they share stories as though they survived the landing in Normandy on D-Day. The fact is, actual American soldiers have put their lives on the line so we wouldn’t have to run through barb-wire-laden mud pits. Participation in an event like a Viking Scramble is sort of like saying our forefathers died for nothing.

Have you ever competed in a Viking-Scramble-like event? What were you thinking?!
