A middle distance triathlon covers 1.9 km of swimming, 90 km on the bike and a 21.1 km run — a serious test of endurance that attracts athletes looking to push beyond sprint racing without committing to a full iron-distance event. South America has a rich and growing calendar of these races, spread across a wide range of climates and settings, from coastal cities to river towns deep inland. Races are spread across much of the year, with strong clusters from July through to November and further events in January, March and April. Brazil alone accounts for a large share of the calendar, with races in cities including Rio de Janeiro, Florianópolis, Fortaleza and Aracaju. Beyond Brazil, athletes can race in Colombia, Argentina, Ecuador, Chile, Paraguay, Uruguay and Peru. SportsPal brings the full calendar together in one place, covering every organiser — including IRONMAN and Challenge — so you can compare dates and locations without checking multiple sites.
