A 10k run and swim in North Wales: with mountains, a clear sandy estuary and a fast tide pushing you on, this is the fastest 10k in the land – with run-swim and run options too.
Set in North Wales on the edge of Snowdonia, this is the most beautiful swim we have ever found. 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.
The whole swim 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.
For those who fancy a challenge, there is the chance to take part in The Outdoor Swimming Society’s only Run-swim event. Run-swimmers will run from Penmaenpool to Barmouth, take a break and then join the main swimming event.
The swim and run ends at Penmaenpool, to change, gather for hot food warm up on fire pits and in hot tubs. Our swims are always about the journey and what a journey this is. It took us 7 years of looking to find a swim route that rivals the Dart 10k, and this is it.
Everyone is welcome – swimmers of all ages, disabled swimmers, and swimmers from around the world. The swim and run-swim are open to all who can swim a mile in 35 minutes or less and run 11km in under 1hr 10 minutes. There is no time limit for the run-only event.
