Organiser's Description

Swim, cycle and run over 1,055 km from Loch Ness to London, and tackle this seven-legged beast! Spanning 7 days, the Monster Triathlon is the UK’s ultimate multi-sport challenge. It starts with a 5k swim in Loch Ness, then 5 stunning days covering 1,000k on the bike, finishing with a 50k ultra-marathon run along the Thames, from Windsor to Richmond. For those unable to tackle the beast in one go we are offering Swim, Cycle and Run only packages this year.

You’ll pass lakes, climb mountains, ride past fields, fly through villages, cross rivers and conquer hills. As well as being an epic challenge, The Monster Triathlon also highlights the beauty and diversity of the UK. 7 days of meticulously planned routes, with full support teams in attendance at every start, finish, and on route. 5-11 July.
