15. Mud Mile
True to its name, Mud Mile is a mud run, but really only lasts a quarter mile. However, after just a fraction of the distance, you’ll be ready for it to end. Wade and run through a series of waist deep water pits about 15 yards wide. A five-foot wall separates each pit that’s necessary to scale to reach the next pit. Be careful of the uneven, muddy bottom with hidden random holes and drop offs. At the end crawl through a short section of mud before reaching a dry trail.
Hint: Before you tackle Mud Mile, take a second and tie your shoes extra tight. You’ll be glad you did. Suction forces from the friction of the mud and the wrenching of your foot through it threaten to suck your shoe right off.
