Top 9 UK triathlons for challenging open-water swims

March 15, 2021 0 By PENTICTONLAWYERS

we decided to take a look at some of the other difficult open-water swims around the UK, starting with a brisk dip north of the border in the Firth of Forth. 


Rat Race City to Summit

What it is: A newish point-to-point triathlon that starts outside Edinburgh and finishes with a run to the summit of Britain’s highest mountain, Ben Nevis.

Why the swim’s tough: The race starts with a 3.8km swim in the Firth of Forth, which flows into the decidedly nippy North Sea. The water at last year’s event was a lower-than-expected 9ºC, causing the organisers to shorten the swim leg down to 1km.

The Brutal 

What it is: With half, full and double-Iron distances on offer, and all requiring a run up Mount Snowden, this is viewed by many UK triathletes as the country’s hardest race.

Why the swim’s tough: Cold, long (in the case of the double, very long) yet undeniably scenic late season swim in Snowdonia.

We also rate The Brutal as the toughest ironman distance race in the world
