Tri2O Swim Centre

The Tri2O Swim Centre (opening hours below) is open to Triathletes and Open Water Swimmers of all abilities. Whether you're an absolute novice looking to take on your first open water swim or a seasoned English Channel swimmer, we look forward to welcoming you. Now in our 9th season running the Swim Centre, we still love helping our customers smash their goals...whether that is simply getting in to the lake and completing that first lap, or building up to that sub 10 hour Ironman or Marathon Swim!

The on-site Tri2O Shop and Wetsuit Fitting Centre carries a comprehensive range of wetsuits and accessories from blueseventy, Orca & Huub.
We offer a complimentary wetsuit fitting service and what sets us apart is that we fundamentally believe any swimmer purchasing a new wetsuit should be able to try it on before they buy, so that's what we offer. Our team will ensure you select the right wetsuit for your requirements, help you to put it on correctly and depending on demo suit availability, even 'try before buy'.

The lake water temperature is measured and updated daily on our Home Page at Why not set us up as one of your 'favourites' and have a quick glance before you head over for a swim....then you can decide if you need those booties or not! You can also get regular updates by following us on Twitter or Facebook.
