Amphibian Open Water Swim Challenge

The Amphibian is our flagship event with the unique format of swimming 1km in the Blue Lagoon followed by a 100m run is a challenge to see if you can Evolve from the water and be equally as efficient running on land like an true Amphibian! How many laps can you do? 

New for this year as due to lockdown we are all at different levels of fitness from where we would usually be we've decided to change the format little. This year rather than entering a specific distance you enter for a flat fee and on the day you can do as much or as little as you feel like (min 1km, Max 10km). So if you would normally swim 5km but after 3km you feel you've had a enough you can cross the line to stop your time! You can take it a lap at a time and see how far you get. 

Don't forget that after each 1km swim you need to run 100m before diving in for another lap or to run across the finish line to stop your race time!

It's very simple Swim, Run, Repeat!!

(Due to Covid-19 and on the advice of the governing bodies this is a participation/challenge event therefore there will be no prizes/awards for specific distances).
