Slateman Duathlon

***COVID-19 Update - In light of the ongoing health crisis in the UK and globally, we have issued a statement here***

The Slateman Duathlon is the perfect option for competitors who want to experience the thrill of the legendary Slateman without having to face the iconic swim in Llyn Padarn.

The Sprint Duathlon created a buzz amongst duathletes in it's first year and we've since had huge demand for a Standard Duathlon so in 2020 we will be running both distance events. Run on a combination of trail and road through the historic slate quarries and cycle over the mountain passes; all in the shadow of Wales’ highest peak, Snowdon. The sprint distance bike course is entirely on fully closed roads making it a perfect introduction to cycling Snowdonia’s famous mountain passes. These races are set to become a highlight of the Duathlon season.

At the Slateman Duathlon we are proud to be hosting the ETU Sprint Distance Duathlon Qualifier. 

This is your chance to claim a place on the startline for the 2021 ETU Sprint Distance World Championship. This race entry is open to all British Triathlon Members. To be eligible for qualification, athletes must have a valid membership and have registered their intent to qualify with British Triathlon by 5pm on the Friday before (Friday 12th June). Register intent to qualify here.
