Tri Larks Year in Brief 2017

The year started with eleven members taking part in the Ironman 70.3 in Barcelona in May.

We saw two members complete their first 70.3 and one member winning the outright fasted runner, across both genders and finishing her first 70.3 in fourth place.

The year also saw two members qualify and take part in the 70.3 World Final in Tennessee, and we had a further two members qualifier for the European Aquathlon and Standard Distance Final and a further two members taking the plunge and completing in their first every Triathlon.

Triathlon Diary of events 2018

So what’s in a triathlon anyway?

There are 4 different triathlon distances, distance

Sprint Distance

A sprint-distance triathlon is often the best way for a new triathlete to have positive experience in their first event. A typical sprint distance event consists of 400 to meters of swimming, 20 to 25 km of cycling and typically a 5 km run. This distance makes completing the event quite manageable for fit and soon-to-be fit athletes.

Olympic Distance

In the late 1980s, a 1.5 kilometer swim, 40 kilometer bike ride and a 10 kilometer run (0.9 miles swimming, 24.8 miles of cycling and 6.2 miles of running) was often called “International-Distance Triathlon” because that distance was accepted as the international standard and used at the first Triathlon World Championship. That championship was held August 6, 1989 in Avignon, France and the winners were Erin Baker of New Zealand and Mark Allen of the United States.

In 1994 the International Triathlon Union (ITU), lead by president Les McDonald, convinced the International Olympic Committee to make triathlon an Olympic sport for the Sydney Games of 2000. The title for the “International-Distance Triathlon” was changed to Olympic-distance. Today, an Olympic-distance triathlon remains a 1.5-kilometer swim, 40-kilometer bike ride and a 10-kilometer run.

Half-Ironman Distance

For athletes looking to increase their personal endurance challenge, without leaping to an Ironman-distance event, a half-Ironman event is perfect. These events are typically 1.2 miles of swimming, 56 miles of cycling and 13.1 miles of running.

Plenty of top-shelf half-Ironman distance races around the country are hosted by outstanding race directors.

Half-Ironman distance events hosted by the World Triathlon Corporation are called “70.3” events, representing the total distance, in miles, covered in the event and representing a trademarked business name.

Ironman Distance

The original sport distances for an Ironman race, were established by John Collins, and the first Ironman race was held in 1978 on the island of Oahu, Hawaii. These distances remain the standard for Ironman racing today.

This gold-standard endurance event is 2.4-miles of swimming followed by a 112-mile bike ride and finally topped off with a 26.2-mile run. Only events owned by the World Triathlon Corporation may have “Ironman” in the title as the word “Ironman” is a registered trademark.
