Open water swimming.

We currently have access to Glyn Neath Lakes and is available for members of Celtic Tri Triathlon Club to carryout swimming there, once a member has registered with the club.

Other open water venues we use include; the North Dock at Llanelli and sea swimming at Aberavon, Mumbles and Gower. Dates and time of these swims will be posted on the Celtic Tri Facebook Group.

Open Water Swimming at Glyn Neath lakes
This will be starting in May, once the water temperature rises above 11°C, as NO swimming is allowed to take place until then.

As a club we pay an annual fee to the owner of Glyn Neath lakes and it’s based on our club size. At present this facility is FREE for our club members to swim at.

Any members interested in swimming at Glynneath Lakes will be required to register with the club before they can swim.

Registration is now open until May 13th, after this period registration can still be made but there may be a delay in approving them.
You must be a paid up Celtic Tri member to register.

As this venue is at a remote location and not managed, the risks on swimming there will fall on the individual. You will be required to sign a disclaimer and follow the guidelines set by the owner and the committee of Celtic Tri before swimming there.

Full details of the Guidelines, Risk Assessments, Emergency Action Plan and a downloadable Disclaimer form are available from the members only area. Click here to view/download docs
