Couldn't talk myself into a ride so went and did some mapping at Forest Farm instead. Undergrowth not as much of an issue than I was expecting and found some interesting features.

MDC Waun Fach. Legendary route that I'd not done. Lovely evening but struggled a lot on the climb, especially with no warm up and then was in quad save mode all the way down. Shame, as the descent was lovely.
