About the event

The Brutal Extreme Triathlons start in the beautiful Lake Padarn. The bike course goes through stunning scenery and over some challenging hills. And finally, the run takes you on a undulating trail round the lake and up and down Wales' highest mountain, Snowdon.

This is 'The World's Toughest Triathlon' (as voted for by 220 Triathlon in 2017) but it is renowned for it's low-key and friendly vibe. Every athlete, whether it's your first triathlon or 21st, will feel the massive support from not only the event crew, but the other competitors too. The challenging terrain and breathtaking scenery creates an awesome experience that will stay with you long after the aches and blisters have gone!

The distances available are Half, Full, Double, Triple and Quin* You can enter all of these events as a solo or in a team (2 - 4 members)
