I did this event when it first entered the atlanta scene 10 yrs ago and now again, on it’s 10th anniversary. it has grown by thousands, but the fun is still the same. i did it with my brother again, and we had such a great time. you come up with a goofy team name. then one of you starts the race mtn biking, the other running. at checkpoints along the 6 mile course, you switch between biking and running, but do so after completing an easy obstacle. you switch like this the entire race, but at the end, you meet up with your buddy and crawl through and enormous mud pit, to then cross the finish line together, smiling ear to ear, just for the fun of it. then you get your 2 free beers, shower off at the water hoses, and leave, knowing there’s always a muddy buddy out there for you. co-ed teams, boys and girls only teams, old, young, fat, skinny, slow, fast… anyone can do this race as long as you want to have some fun.
