Open water 1500m / 40k / 10k The Bala Triathlon is set in the lakeside town of Bala in beautiful North Wales. The setting is excellent with plenty of space for transition and parking at the nearby rugby club offering additional shower facilities. The swim is in Llyn Tegid, which is approximately 10 miles in circumference (wet suits compulsory). The bike section is fast and on a closed road with beautiful scenery, while the run uses the cycle track alongside the closed road enabling competitors a view of both disciplines.
