Spanning 7 days, the Monster Triathlon is the UK’s ultimate multi-sport challenge
The Monster Triathlon offers the ultimate epic endurance challenge, returning in June 2025.
Your challenge begins when you take on a 5km swim in Loch Ness, before 5 stunning days on the bike and the final push into London – a 50k ultra-marathon.
As you tackle the challenge of the Monster Triathlon you’ll conquer the very best the UK has to offer, from epic mountain passes in the
Scottish Highlands to the expansive lakes of the Lake District, from the rolling Chiltern hills to idyllic villages in the midlands before a
grand finish in the capital. Our monster challenge will showcase the beauty and diversity of the UK as you take on our 1,055km beast.
