Whether fleeing from ghouls in The Zombie Run or tackling obstacles as part of a Spartan Race, there are some fun races to participate in. These two are traveling events, available to residents across the U.S. as of 2015.
If zombies are your thing, then try The Zombie Run. Run the 3.1 mile trail and conquer obstacles as you flee from people dressed as brain-thirsty zombies, all under the cover of night. Alternatively, try the 20+ obstacles of the Spartan Race. These races offer the choice of a 3+, 8+, or 12+ mile course, providing appropriate challenges for a wide range of fitness levels.
