Trail Reviews

July 6, 2023, Talybont - Brecons MTB

Starting in Talybont we took the super gentle climb up, the gradient is really gentle and great for groups to ride together. At the top the path opened up, we then cruised down to find a technical descent in the woods. Running out of time we bombed back on the road past the reservoir back to Talybont.
