Join Mid Sussex Tri Club

Mid Sussex Tri Club have been organising open water swimming sessions at Ardingly Reservoir for over 15 years and have recently passed over the running of these sessions to the Activity Centre. We love swimming in the reservoir and members receive a discount on the price of their swims.

We are a thriving triathlon club based in Mid Sussex and include all levels of triathlete in our ranks, from those training for their first event to athletes competing at GB age group level. We have a full timetable of coached training sessions available to members which include also include pool swims, spin bike sessions, run and outdoor cycle groups – take a look at our website for more details.

You’ll see us at the reservoir – particularly on Saturday mornings and Tuesday evenings over the summer – so come and say hello. We’re a social bunch and love introducing new people to the sport and helping them to start their own multi-sport adventure!
