The Gilwern Grunt

Date & Location

Garn-yr-erw, S Wales

Organiser’s Description

This 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. There’s the 'Grunt' climb to look forward to, the marvellous, spectacular run around and down from Gilwern Hill, a traverse of 'The Tumble' and an excursion through the larva-like landscape of the canyons of Pwll Du. 8 miles (approx) with 460m ascent. A route for connoisseurs!
