Underwear Marathon?! the 7 Craziest Races Around the Country

If you're a serious runner, there are so many endurance events out there for you. From 5Ks to 10Ks, half marathons to the full 26.2 miles, you can pick a distance and a location and run to your heart's content. But for the fun runner or someone looking to spice up running monotony, there are dozens of themed runs that take the fun of an endurance event to a whole new level. After I complete my first Tough Mudder this weekend, I might check out a few of these to see which one makes me want to continue my running streak. And there are certainly a lot to choose from. From short fun runs with zombies to crazy long obstacle-laden courses even more challenging than the Tough Mudder, there are runs out there for every level of competitor. For most of these, a sense of humor and adventure is mandatory. So if the thought of running mile after mile leaves you uninspired, check out one of the many fun runs out there that are guaranteed to spice up those monotonous miles.
