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.
