Triathlon races worldwide

Triathlon spans sprint distances under an hour and full IRONMAN events that take all day. The big franchises are IRONMAN (full 226 km and 70.3 half-distance), Challenge Family (mostly long course in Europe), and the regional national federation series. Kona remains the world championship target for IRONMAN-distance racing; St. George and Nice rotate the 70.3 worlds. Below the franchises, indie races at scenic venues — Norseman, Embrunman, Alpe d'Huez Long Course — often have stronger fields and more character than the franchised events at the same distance. If you're new, filter by sprint or Olympic distance and look for races with non-wetsuit-legal water temperatures only if you're confident in open-water swimming.
