Amphibian Open Water Swim Challenge

You might be great in the water or running on the land but how good are you able to EVOLVE after every 1000m swim and then run 100m before diving back in for another lap? Can you keep evolving until you've completed your race distance? The Amphibian Open Water Swim Challenges offer a range of distances so there's something for everyone!

New in 2018 was the 7km event for those who want to up their game from 5km but don't feel quite ready for 10km!

Lake Temp


Last Update 04/07/2020

Minimum Temp for Swimming is 11ºC*

*In the spring we wait until the water is holding at least 14ºC overnight to ensure it remains above the minimum temperature for swimming. 

Wetsuits are mandatory when the water temperature is below 18ºc. Above 18ºc wetsuits are optional but non wetsuit swimmers must used an approved Tow Float. The Blue Lagooners Management reserve the right to request to test the suitability of a swimmers wetsuit or tow float for buoyancy & suitability for swimming and reserve the right to refuse access to the water if a swimmers wetsuit or tow float is deemed unsuitable and/or unsafe for swimming. Please check out our info videos on our open water swimming page that explain why this is so important.
