Yes - due to popular demand it's back again for 2021. The route will be unchanged. A spectacular run around and down from Gilwern Hill, a traverse of “The Tumble” and an excursion through the lava-like landscape of the canyons of Pwll Du... and who could forget the finish up and down the infamous volcano?

This gives an approximate distance of 8 miles.

It really is the most interesting off-road race, with some spectacular scenery set amongst a backdrop of remote moorland-like areas and old quarry workings. A route for connoisseurs! A route for those who like a challenge!

Covid: No one can say at this moment what the 'covid situation' will be by 5th April. However, the event will be fully compliant with both local and national 'covid regulations' at the time. The event may go ahead as an individual time trial with bookable time slots (runners going off at 10 sec intervals) or there may be waves of 6 starting at 10 sec intervals. We will have to wait and see, but rest assured we will ensure there are safe 'covid protocols' in place.
