How Long is a Triathlon?

When thinking about competing in a triathlon, some of the first questions you probably ask are ‘how long is an Olympic triathlon?’, ‘how far do you swim for a triathlon?’ or ‘how many miles is a triathlon?’. At Kitbrix we are here to answer all of your questions so you can find the perfect triathlon race to suit your ability, and get racing!

So, what is a triathlon exactly?

A triathlon is a multi-sport event consisting of three separate disciplines completed one directly after the other. The most common order that triathlons are competed in is swimming - transition 1 - cycling - transition 2 - running. The transitions are usually skimmed over, but they are definitely worth accounting for as they are just as much of the sport as the three disciplines. Transitions can make or break your finishing time! 

Another important thing to note, is there isn’t just one length of triathlon! Triathlons can vary greatly in distance and location, which is what makes this the well-loved and inclusive sport it is. The cycling third of the triathlon is typically the longest, running somewhere in the middle and the swimming third the shortest, the bit that everyone worries about most! 

The four most common triathlon lengths are the Sprint Triathlon, the Standard (also known as the Olympic) Triathlon, the Half-Ironman (also known as 70.3) Triathlon, and lastly the longest, the Ironman Triathlon...

A Duathlon is a race that sandwiches cycling between two blocks of running; run - transition 1 - bike - transition 2- run. Alternatively, an Aquathlon is similar but with swimming; run - transition 1 - swim - transition 2 - run.
