Slateman Triathlon 2024
The Slateman Triathlon is the most iconic adventure triathlon in Wales. Starting in Llanberis; the heart of Eryri (Snowdonia)’s industrial heritage, this is an unparalleled race which combines stunning scenery with epic challenges. 220 Tri Magazine has listed the Slateman amongst the world's best triathlons.
Now staged in June, the warmer water temperatures and a party atmosphere all surrounded by stunning scenery will make this an event not to be missed from any athlete's calendar.
Are you up for the trio? The Slateman is also the first part of our Adventure Series of triathlons & duathlons.
