Columbia, SC

Columbia is dead flat on the coastal plain, so cyclists dominate the scene here—gravel racing like Tico's Gravel Grinder 10K and the Harbison MTB Challenge pull riders into the clay and sand terrain around the Congaree River swamps and state forest 20km east. Runners have the Congaree riverfront parks and flat loops around the downtown lakes, but humidity and heat are constant factors year-round; the adventure race community is strong, with Soda City Adventure Races and Jason's Adventure Bash drawing multisport athletes to longer off-road navigation challenges.
