SportPursuit Slateman10 Duathlon 2021

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. Run, bike and run again on a combination of trail and road through the historic slate quarries and over mountain passes; all in the shadow of Wales’ highest peak, Snowdon.

We are proud to be hosting the Europe Triathlon Sprint Distance Duathlon Qualifier at The Slateman in 2021.
