I'll post up some images from Friday's 3hrs (dry & fast) ride on the Pen's 2x Loops followed by the (wet) Marin Trail in the afternoon.
I if you are looking for a cracking XC circuit that flows brilliantly, Pen's the one. I / we had an absolute hoot. One to do again, for sure, and rewards swift progress, so testing of ones fitness if you do both loops at one sitting.
Marin? Zzzzzz. In fairness it was chucking it down after lunch, I was a little fatigued and needed stimlating but what a boring trail that was. I bailed 1.25hrs into it, at the furthest point from the lower car park, so maybe there was more to it than I rode.
Up Snowdon on the Saturday in less than 2hrs which was far better than expected, then down the Ranger's Path. Back up 500m and over up the saddle with a long continous decent back to the car park at the train station. A good ride.
