Triathlons in the UK

The triathlon is a multi-sport event combining swimming, cycling and running. The length and duration of these events can vary greatly, ranging from just a few miles to 140 plus. In addition, conditions in competition can differ from event to event. The swim could be in an indoor pool or the sea, and cycling or running on flat coastal roads or rolling countryside hills.

The UK plays host to some of the best triathlon events in the world. Large scale events such as the ITU Worlds Triathlon Leeds and London Triathlon host athletes of all levels of experience with big crowds building a buzzing atmosphere.

What’s the best UK triathlon event for me?

On Let's Do This, you can refine your search for a triathlon by exploring different race distances.

The Super-Sprint distance (400m, 10k, 2.5k) and Sprint distance (750m, 20k, 5k) triathlons are great for beginners looking to explore multi-sport. These events can be attempted without much prior training. But if you want to be competitive you should practice your transitions as they can make a big difference to your time.

Olympic distance triathlons (1.5k, 40k, 10k) are the standard distance for international competition. To be competitive here, you’ll need to take your training seriously. If you can finish one of these in under 3 hours, kudos to you.

The final two distances are the Middle Distance / Half Ironman (1.9k, 90k, 21.1k) and the Full Distance / Ironman (3.8k, 180k, 42.2k). Finishing these events is an achievement in itself. If you have trained well for a Half Ironman you could be pushing for under 6 hours for men and 7 for women. For the full distance, anything under the 17hr cut off point is a solid accomplishment, but under 13 hours (men) and 14 hours (women) deserves serious respect.
