Off The Tarmac Trail Marathon & 10 Mile
The Off The Tarmac Trail Marathon & 10 Mile Race on 16 May 2026 are both on trails through the Brecon Beacons.
The Marathon course starts/finishes at Parkwood on a looped course that takes in Pen Y Fan from Graig Fan Ddu, before heading up Fan Y Big and heading over to Talybont Reservoir for the final climb up Tor y Foel.
The 10 mile route follows the OTT Marathon Trail route to Checkpoint 1. There is a mandatory check-in at Checkpoint 1 before you leave the marathoners to follow the forestry tracks back to the start line.
This is a cup-free event – bring your own cup/water bottle for refilling at aid stations during the race. Refer to the event website for compulsory kit details.
