Obstacle Course Racing races worldwide

Obstacle course racing puts running between purpose-built obstacles: walls, monkey bars, sandbag carries, rope climbs, mud crawls. Spartan Race is the largest series, with Sprint (5 km), Super (10 km), Beast (21 km), and Ultra (50 km) distances plus a championship season. Tough Mudder and DEKA fill out the rest of the format. Distances are a guideline — actual distance, terrain, and obstacle count vary by venue. Most events are non-competitive at the front and entirely about the experience further back. If you're picking a first race, filter by Sprint or 5 km — full Beasts and Ultras assume serious terrain and grip strength.
