What Is Triathlon?

Strange question on a triathlon website? But let's find out and dive in a little deeper.

Novice triathletes often favour the familiar environment of a pool swim. However, Qatar's beautiful beaches and comfortable water temperatures warrant getting confident in open water.
Novice triathletes often favour races with a pool swim as it is an environment they are familiar with. However, Qatar's beautiful beaches and comfortable water temperatures certainly warrant learning to get confident with open water.

A triathlon is a continuous timed race combining the three disciplines of swimming, cycling and running in that order. Between each, you have a 'transition', triathlon’s so-called fourth discipline. The first transition between swim and bike is known as T1 and the final transition between cycle and run is known as T2. Your time to change from being a swimmer to cyclist and cyclist to runner is included in your overall time and a good transition routine shaves minutes off your time. The good news is that you can practice and get faster in transition without having to be any fitter!  

TriClub Doha is also active in other multisport events: Duathlon (run/bike/run), aquathlon (run/swim/run or swim/run), and aquabike (swim/bike)


Triathlon and aquathlon swims can take place in swimming pools or in the sea, lakes and rivers. These open water swims may require triathletes to wear a wetsuit but in Qatar, most events are deemed 'wetsuit-optional' or 'non-wetsuit'. World Triathlon rules dictate the temperature at which a wetsuit is required according to distance, water and air temperature. Therefore, you could have an event where swimming 400m without a wetsuit is allowed but swimming 1500m is not. For most events in cooler countries a wetsuit is recommended, even when not required, as it will give you the advantage of buoyancy as well as warmth.


Triathlons aren't always a fixed distance but there are some common standards. Distances below are expressed as swim/bike/run. Many events offer multiple distance competitions. For example, TriClub Doha's Education City Triathlons have super-sprint and sprint distances, and also shorter distances for beginners and kids.

  • Super sprint = 400m/10km/2.5km
  • Sprint distance = 750m/20km/5km
  • Olympic or standard distance = 1500m/40km/10km
  • Half ironman or Ironman 70.3 = 1900m/90km/21km
  • T100 = 2000m/80km/18km
  • Ironman distance = 3800m/180km/42km

Novice triathletes come in many shapes, sizes, and fitness levels. You may have embarked upon your triathlon challenge as part of a change of direction in your life, you may have migrated to your first time triathlon from another high endurance sport, or a beginner’s triathlon may simply be the next step for you. Whatever your reasons, you are ultimately the best judge of whether a sprint triathlon, Olympic, middle distance or a long-distance triathlon will suit you best.
