Monster Triathlon

550 miles

Created in 2016 by a group of oil company employees and African education charity Sabre Trust, the Monster is a triathlon with a big difference - it covers 550 miles over seven days.

If you choose to raise funds, why not consider the Sabre Trust - and enjoy a 12% discount on your ticket. This fantastic small charity helps kindergarten children in Ghana to get a bright start to their education.

Another 5 months and 28 days till the start.


You can tackle the seven-legged beast on your own - or as part of a team of between two and seven members. Come on, one day each already sounds a lot more manageable!
