Fort Gordon, Georgia (United States of America) - "Marine Mud Challenge". Join us for the 2026 Marine Mud Challenge, proudly presented by Five Star Nutrition. This 4-mile off-road adventure features more than 30 obstacles, a stream crossing, rolling hills, and, of course, plenty of mud. Whether you're in it to compete or just looking for a fun challenge, there's a place for you on the course. Think you've got what it takes to compete? The competitive categories are for the runners who are truly in it to win it - the ones ready to run the whole course and conquer every obstacle. You'll register solo, but if you want your crew by your side, just meet up at the start line and take off together. Every runner gets electronic timing, and participants must be 13 or older, though younger mud warriors can join with parent or guardian approval. Feeling helpful instead of muddy? We'd love volunteers too. Just choose the volunteer option, pick the role and times that fit your schedule, and a coordinator will reach out with the details. The first 800 registrants will receive t-shirts. https://gordon.armymwr.com/view-event/marine-mud-challenge/7214975/108254
