Slateman Swim

Llyn Padarn is a magnificent glacially formed lake nestled admist some of Snowdonia's most spectacular scenery. The lake is approximately 2 miles (3.2 km) long and covers about 240 acres making it one of the largest natural lakes in Wales. On the southern bank sits the busy village of Llanberis whilst on the opposite side the Llanberis Lake Railway runs through the spectacular woodland of the Padarn Country Park.

The whole of Llyn Padarn is a Site of Special Scientific Interest and home to a rare type of fish called Arctic Charr. Legend has it that is was brought here from Rome by the early Christians while scientists believe it has survived in the lake since the ice age; either way it's a pretty robust fish that's been around for some time. It inhabits the depths of the lake which at a deepest point of 29m means they're not going to interfere with your swim.

With it's crystal clear waters and incredible views Llyn Padarn has become infamous as one of the best Open Water Swimming spots in the UK and we're really excited to bring these Open Water Swimming events to the Slateman Triathlon weekend.

Slateman Triathlon

Starting in Llanberis; the heart of Snowdonia’s industrial history the Triathlon combines stunning scenery with epic challenges. Swim in the fresh water of Llyn Padarn, run on a combination of trail and road through the historic slate quarries and cycle over the mountain passes; all in the shadow of Wales’ highest peak, Snowdon. The sprint distance bike course is entirely on fully closed roads making it a perfect introduction to cycling Snowdonia’s famous mountain passes.

Meet the organiser

Always Aim High Events was founded in 2010 by Tim Lloyd and Nigel 'Kenny' Kendrick. The first event was the now iconic Slateman Triathlon 2011 attracting just over 400 competitors (it now regularly exceeds 1,000), with a vision that included the Snowman and Sandman - the three events which now make up the Adventure Triathlon Series. From that one event we now host 34 all inclusive events over 9 weekends, with many more planned for 2019 and beyond. In 2015 Always Aim High Community Events was set up as a not for profit organisation to help with engaging with and hosting local community events. At Always Aim High we are extremely proud about delivering the UK's ultimate triathlon, cycling, running and swimming challenges in the most beautiful and iconic locations that we can find. From epic mountain, coastal and city triathlons, to breathtaking cycle sportives which cover the length and bredth of Snowdonia, there's something for everyone at Always Aim High Events!
