Lots of Mud! Lots of Obstacles! Hill climbs, mud pits, fire hoses and fun. If you’ve missed any of these, you’re missing out on the dirtiest fun you’ll ever have with a 5K race! It’s a pretty muddy affair! Many folks ask how tough is the course? It can be as hard or as easy as you want it to be. One thing is for sure. When you run this race, the Marines will make sure you finish it. Part of the Marines Creed is to never leave another Marine behind. And for this event, no runners will be left behind!
