What is a Triathlon?

The first recorded triathlon was in California on September 24, 1974.  It was organised by the San Diego Track and Field Club at Mission Bay and was created as an alternative to the rigors of athletic training on the track. Since this, Triathlon has developed into one of the fastest growing sports in the world, and one that can be enjoyed by all ages and abilities.

Triathlon is an activity that combines swimming, cycling, and running in one event. The Olympic, or “standard” distance in triathlon is a 1500 metre swim, 40 kilometre bike, and 10 kilometre run.

There are many variations of a Triathlon or multisport event that can be done as an individual or as part of a team. The table below gives a good overview of the various types of events and distances:

Triathlons are organised through independent events organisers, state triathlon associations and clubs. They are run at local, state, national and international levels. Triathlon events in Australia range from enticer or novice events right through to ITU World Championship races.

One reason why Triathlon is so appealing to all is because of its unique “age group” concept that is built into the very fabric of the sport. All Triathlon events are traditionally divided into 5 year age categories, so you will take part in the same race as your friends, your colleagues and your family regardless of their age and ability. 

Triathlon truly is a proud sport for all. Have a read of the Triathlon Pathway to see how you can get involved.
