A half distance triathlon, also known as âmiddle distanceâ and sometimes referred to as a 70.3 (named for the total number of miles travelled) covers, as the name suggests, half the distance of the Iron-man. The required distances are a 1.93 km (1.2 miles) swim, a 90 km (56 miles) cycle and 21.9 km (13.1 mile) run.he Olympic distance triathlon, also known as âinternational distanceâ requires a 1.5 km (0.93 mile) swim, a 40 km (24.8 mile) cycle and a 10 km (6.2 mile) run.
Triathlons range in all sorts of distances. Sprints typically have (400-800 yard swim, 10-20 mile bike, and 2-5 mile runs). Then you have international distance: (1.5 km swim, 40km bike, and 10k run). So you have to know how far you will need to cover in a race to safely know how long you should train for that event.
