An off-road triathlon involves open water swimming, mountain biking, and trail running. The courses traverse rough terrain—single track, woodland paths, and rocky slopes—and challenge athletes with steep descents and difficult terrain.
Unlike traditional road triathlons, off-road triathlons reward bike-handling skill, agility, and adaptation to surfaces. Transition zones may be demanding and aid stations less frequent to promote self-sufficiency in navigating the course as well as in fueling. Xterra triathlons and cross-tris are popular varieties, distances adjusted for technical challenge. Off-road triathlons appeal to athletes seeking adventure and skill-based endurance racing.
