It is a journey, not a lap.
You are not returning to a start line. Every day you are further south and closer to London. By Saturday you are 1,055km from where you began, at the other end of the country.

This is not a race you survive in a day
Monster Triathlon is a fully supported seven-day journey across Britain. It opens with a 5km swim in Loch Ness, rides south for five days and finishes with a 50km run along the Thames into London.
You take it on one stage at a time. Your accommodation, your meals, your baggage, your mechanical support and your medical cover are handled across the week. Your job is to keep moving south.
Seven stages. One complete challenge.
02
It is not a race.
The swim and the cycling stages are not timed. The 2027 final run features chip timing, but completion and the shared experience are the point. Groups form at different speeds and nobody is racing you.
03
It is supported, not easy.
We handle the logistics. You still have to ride 1,000km in five days. Both of those things are true at the same time, and we would rather say so.

What Monsters say
“It’s not a race and the camaraderie amongst the group was fantastic. Support from Sam and the team was second to none.”
“This is a social event, unlike other single day long distance triathlons.”
“I was 62 when I did it and not fast as a swimmer or cyclist but never felt left behind.”
