The Course

Love SwimRun Llanberis will take place in Padarn Country Park, Llanberis, Snowdonia National Park, North Wales. The multi transition course in North Wales will involve a total of approximately 3.5km of swimming and 12.5km of running (Sprint course is 1.3km of swimming and 4.7km of running). The running route will take in some of Snowdonia’s most stunning scenery and views on mainly off road terrain, including beautiful woodland, a historic monument and a tough climb up into the old slate quarries that tower above the valley. The swim sections will all take place in Llyn Padarn, entering and exiting the lake at various locations, so by the time you reach the finish line you will have swum the entire length and explored every corner! The course will be fully marked.

Spectator info

Spectators are welcome at Love SwimRun events. Please park considerately and use the parking bays in Y Glyn. Please do not park on the road. There are plenty of good spots from which to support your friends. After seeing the race start at Y Glyn, we recommend that you walk down to the south end of the lake where you’ll be able to see them finishing the first long run and setting off on the second swim. You’ll have plenty of time to walk back to Y Glyn to see the race finishers. If you are feeling energetic you could even walk all the way around the lake! We would advise you to dress warmly and wear suitable footwear for walking on rough ground. If you take any photos or videos we would love to see them!
