A triathlon has 3 stages to it, a swim, cycle and a run. These can be a varying distances, but it is aimed at being an endurance event, where competitors need stamina and mental will power to get them through the pain.

Triathlons are held all over the world for differing abilities, the most famous of which is the Iron Man competition, which is the grand daddy of all the events.

Many competitors have one discipline that they are weaker at and so try to gain time in the other stages. The transition phase of the race is paramount to maintaining a good time. After the swim you must run and take off your wetsuit, grab your bike, run with it and then jump on and get your feet into the shoes which are already attached to the bike. It takes some skill to do this and many people lose valuable time at this part of the race.
