Come conquer Sudbury’s crater in our 21k or 63k Ultra Marathon that offers the most beautiful terrain. The 63K and the 21K trail runs will consist of 21km laps, all safely contained within the trail system of beautiful Kivi Park located in Sudbury, Ontario. The laps will include a mix of double-track crusher dust ski trails and challenging single-track hiking trails. The course will take athletes across iconic vistas of the Canadian Shield, showcasing the region’s famous rock, pine forests, and unique geography that once inspired NASA to send their astronauts here for training. The XTERRA Conquer the Crater off-road triathlon and trail running weekend is the only race on the XTERRA World Tour that donates 100 per cent of its proceeds to charity — and that charity is making an immediate, positive impact on local families who need it most.
