All aboard the swim train!
Catch the narrow gauge train to the end of Llyn Padarn to start your swim for a truly unique experience!

We have a mid length option too!
Entries are currently closed. Until we have a better idea of the Covid-19 situation next year, and if or how our swim events will run, we are unable to take any further entries. Hopefully by spring we will have a better idea what will be possible and will be able to release further entries then. Please keep a eye on this page and on social media for updates. We apologise for any disappointment or inconvenience.

Love SwimRun and The Big Welsh Swim everyday vinyl printed logo t-shirts and hoodies are available for mail order in the Love SwimRun shop. Males sizes seem accurate. Female sizes come up small, so if you like a fitted look order your normal size or if you like a slightly looser fit go for a size up (eg for size 10: Small = fitted, Medium = looser fit).

Our Charity Partner – The Marine Conservation Society
We are so pleased to be supporting The Marine Conservation Society (MCS). The MCS is the UK’s leading charity for the protection of our seas, shores and wildlife. Our seas are under immense pressure: too many fish are being taken out, too much rubbish is being thrown in and too little is being done to protect marine wildlife and fish stocks.
Our UK seas and coasts are amongst the most diverse and beautiful on the planet, playing host to dolphins, sharks, whales and turtles. Over half of the UK’s wildlife resides within our seas and many other species such as seabirds rely on them for their survival.
Please help the MCS protect and conserve our precious marine wildlife by selecting to make a donation when you enter. Every little bit will help and every penny will go straight to the MCS. If you are interested in raising sponsorship funds for the MCS in return for a FREE ENTRY please email email@example.com.
Prizes & food!
Hot drinks, snacks and delicious hot food will be available to buy when you finish your race. All competitors will receive a Big Welsh Swim souvenir and a Wild Trail bar at the finish line. Prizes from Zone3 and Love SwimRun will be awarded to the first 3 male and female swimmers in each wetsuit distance category, and first three swimmers in the non-wetsuit category. Prizes must be collected on the day and no cash alternative to the prizes will be offered.
