Swim then run (aka splash and dash) in these triathlon-style events without the cycling leg.

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.
