2026 Square Lake 70.3
An honest, scenic, and now USAT-certified half-distance triathlon. Swim in the crystal-clear waters of Square Lake, tackle the rolling hills of Stillwater on quiet roads, and enjoy fully stocked aid stations along the way. With bottle exchanges every 13.5 miles on the bike and 1.5 miles on the run and a post-race barbecue waiting at the finish, it’s no wonder this race is a Midwest favorite.
