Aquathlons in the UK

Aquathlons are a bit like a triathlon but without the bike leg and are very similar to swimruns - but with aquathlons you can change into running gear at the transition. Most events are a swim-run format (also known as splash and dash) but there are also some run-swim-run events. Select your location to find aquathlons in your area, read more about the distances below or scroll down for events coming up.

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
