Every year in September the Greater Columbia Marine Foundation hosts the largest Mud Run in the Southeast. The race attracts thousands of people from all over the Southeast and beyond. The Ultimate Challenge Mud Run is over 4.2 miles, and has 30 obstacles that have to be crossed by each team requiring team work and a lot of determination. The 4.2 mile course is an all-terrain race conducted on dirt roads, improved and unimproved trails through the training area. These trails include mud holes, walls, trenches and other obstacles that require swimming, crawling, climbing and jumping. Some people come to compete, but many come just to complete!
