July 20, 2021, The Gap - The Brecons & Black

Route taken from Komoot, This route has so much to offer, however couldn’t follow completely as it’s overgrown in a few areas, however Garmin was set to re-route, so no issues. Started from the road, switch back on to the Canal, then steep initial climb up variable loose dirt & tree routes. The route generally keeps climbing & peaks out at the route name ‘The Gap’ between 2 high peaks (either options would require more hike a bike stuff). The descent was great fun, however initial part requires negotiating a few hundred meters of large rocks/boulders, then becomes much easier & can easily increase speed to enjoy some constant flow until getting to the gate(s). The route indicates another narrow passage via a small gate, however this is hugely overgrown & it’s now not possible to ride. Followed the road to the left & linked back up with the route. Final part is jumping back on the canal & riding back to the /start/finish point. Fantastic looped route, if wanted to really enjoy & stop a few times, give your self 4 hrs to be absolutely sure.
