Follow in the footsteps of the North Wales quarrymen on a 5km route on Saturday, 13 June 2020 that takes you round the historic Dinorwic Slate Quarry in Llanberis.
The route oozes atmosphere as you run through the moody surroundings passing the relics of tunnels, terraces, inclined planes and abandoned machinery. There is no other run where history and industrial archeology meet such incredible views with the outlook stretching down to the lakes and across to Snowdon.
The climbs are tough but the reward is high - are you ready to put your trainers and take a step through history?
This event is held as part of the Slateman Triathlon weekend.
