The UK's toughest triathlon? Deca UK in pictures

Image highlights from the 2,260km Deca UK at Dorney Lake

38km of swimming. 1,800km of biking. 422km of running. Over 10 days. No matter how many times we read them, the numbers of Deca UK continue to astound.

Launched by Brutal Events' Claire Smith last year (whose Brutal is one of the toughest irons in the world) and making its debut in October 2017, the inaugural race took over Eton's Dorney Lake – usually a beginner-triathlon honeypot – and attracted some of the most hardcore triathletes from around the globe, with the UK's 100+ iron finisher, Anthony Gerundini, naturally on the start line.

Are these the 7 hardest triathlons in the world?


But after 158:09:04 hours of racing, it would be Ireland's Gerard Predergast who took the honours, and in the process becoming only the second-ever Irish person to complete a deca tri in 10 days.

The father of three completed his 2,260km challenge at 11:06pm on the Friday night, four hours ahead of Dave Kershaw. Rob Duddington was in third place a further four hours back.
