The American triathlon calendar runs from late spring through to December, with the heaviest concentration of races falling in July and August. Cities such as Lake Placid, Boise, Augusta, Louisville, Sandusky and Portland each host events during the summer peak, covering a spread of distances and formats — from the full IRONMAN distance to the 70.3 middle distance and off-road XTERRA events. SportsPal brings major race series — IRONMAN, XTERRA and others — together with independent local races in a single filterable calendar, so you can compare events across months and cities without visiting each organiser's site separately.
