A triathlon is a type of multisport race that involves swimming, biking, and running across long distances. A triathlon race is typically one continuous event with only short breaks in between each activity to allow the athletes time to prepare for the next portion of the triathlon race. Many triathletes wear tri-suits which prevent the need to change outfits between events. The competitors begin with an [open-water swim](https://www.masterclass.com/articles/open-water-swimming-guide) or pool swim. Then, competitors have a short opportunity to change out of their wetsuits or swim caps, put on cycling shoes, and get onto their triathlon bikes. The next portion of the race is a bike ride, taking place either on an off-road course or on city streets. Then the cyclists transition into running shoes to cross the finish line during the running portion of the event.

The triathlon dates back to the 1970s and has become a very popular distance race and world triathlon events are held around the world in places such as in England and Wales in Great Britain as well as in milder climates such as Sydney, Australia; San Diego, California; Tokyo, Japan; and in Kona and Oahu in Hawaii. Triathlon training is extremely rigorous as it requires mastery of three different types of endurance sports across longer distances. Triathlon athletes often follow intense training plans and are careful to consider their hydration and diet. 

Triathlon distances vary based on the event organizer and age group, and race distances are often subject to change. Modified triathlons use different combinations of distance events, such as the aquathlon (running and swimming), the aquabike (swimming and biking), and the duathlon (running, biking, and then running again).

1. __Olympic-distance triathlon__: The Olympic games set the standard for the triathlon with the Olympic triathlon distances involving a swim for 0.93 miles, a cycling route across 24.8 miles, and a run for 6.2 miles.
2. __Sprint-distance triathlon (mini-triathlon)__: A sprint triathlon is half of the Olympic distances. It includes a swim for 0.5 miles, a cycling route across 12.4 miles, and a run for 3.1 miles.
3. __Super-sprint triathlon__: A super sprint triathlon is the shortest triathlon event for entry-level athletes. It has a short course with a 0.25-mile swim, a bike course across 6.2 miles, and a 1.5-mile run.
4. __Ironman triathlon__: The Ironman race originated in Hawaii and was one of the first triathlon events. Today the standard Ironman distances for the Ironman world championships include a swim for 2.4 miles, a cycling route across 112 miles, and a run for 26.2 miles.
5. __Half-Ironman triathlon (half-iron)__: A half-Ironman is a shorter version of the full Ironman event, consisting of a swim for 1.2 miles, a cycling route across 56 miles, and a run for 13.1 miles.
6. __ITU long-distance triathlon__: The ITU triathlons are world championships organized by the International Triathlon Union that involve a swim for 2.5 miles, a cycling route across 74.5 miles, and a run for 18.6 miles.

If you have a previous or pre-existing health condition, consult your physician before beginning an exercise program. Proper exercise technique is essential to ensure the safety and effectiveness of an exercise program, but you may need to modify each exercise to attain optimal results based on your individual needs. Always select a weight that allows you to have full control of your body throughout the movement. When performing any exercise, pay close attention to your body, and stop immediately if you note pain or discomfort.

In order to see continual progress and build body strength, incorporate proper warm-ups, rest, and nutrition into your exercise program. Your results will ultimately be based on your ability to adequately recover from your workouts. Rest for twenty-four to forty-eight hours before training the same muscle groups to allow sufficient recovery.
