Trail Running and ultra races worldwide

Trail and ultra-distance running covers everything that leaves the road, from a 25k forest loop to the multi-day classics like UTMB, Western States, and Hardrock. Distances and vertical gain matter more than finish time — a 50k with 3,000 m of climbing is an entirely different race from a 50k along a canal towpath. The UTMB World Series has consolidated a lot of the qualification chase, but plenty of the best events sit outside it: Diagonale des Fous, Tor des Géants, Lavaredo, Ultra Trail Cape Town. Filter by elevation and distance first, then check for the cutoffs — most trail races have aggressive time limits even for back-of-pack runners.
