Hurly Burly/Bwrlwm Bermo

Set in North Wales on the edge of Snowdonia, this is one of the most beautifully wild river swims you’ll find. It starts on the sandy beach of Barmouth, and takes swimmers underneath Barmouth Bridge, a mile and a half wide iconic railway bridge. The first part of the swim is up the wide and sandy estuary with mountains on either side, and then it’s through ‘the narrows’ and into a more sheltered part of the estuary.

Participants will also have the option to take on a 11km run before the start of the swim. The run route starts at the finish, and finishes at the start of the swim. You’ll see this incredible valley from the banks of this beautiful river and from it’s fast, exciting waters.

The whole swim (10km) takes place on a fast incoming tide that works like a bore to assist your swim. Past the narrows the water speeds up further, and the landscape becomes pastoral, the banks closer to you. Runners will run alongside the estuary on a flat gravel track, taking in the spectacular view along the way.

The swim ends at Penmaenpool, to change, gather for hot food and warm up around the fire pits.
