A middle distance triathlon covers 1.9 km of swimming, 90 km of cycling and 21.1 km of running. In North America, the racing calendar runs from the height of summer well into the following spring, with the busiest cluster falling between July and October across the United States, Canada and Mexico. This page brings together races from every organiser — IRONMAN, T100, Challenge and others — so you can compare the full picture in one place. Events span a wide range of settings, from lake and river swims in cities such as Madison, Louisville and Augusta to open-water courses off Cozumel. Whether you are targeting a fast flat course or a more demanding route, filtering by month or country below will help you find the right race.
