Did this route yesterday (well the first half or bottom o of the figure of 8)
Mynydd route description
Wow – loved it – long gradual climb to begin with but as I was going to be retracing my steps on that bit I was excited at the prospect of riding it last. Once at the top the views were amazing.
Got to the "Steep technical" descent – they don't joke about that one – proper ass over the back wheel, rocky, switchback section which is awesome to ride.
Then a climb to where I should have turned right, but cheated as I didn't have time to do the loop round the next mountain so nipped onto the singletrack which just went on and on and on for about 3km – at one point I did wonder if it was ever going to end. Real swoopy undulating track.
After this into a forest section for a bit of climbing – unfortunately this is where I split my hub open under the immense force my thighs put upon it trying to climb the steep little section. I then had to walk to the top and found that my wheel was rubbing against the chainstay because of the crack so after putting some zip-ties on the hub to avoid it getting any worse I either walked or freewheeled (with my weight on one side of the bike to keep my wheel straight and stop rubbing the chainstay) back to the car about 4 km most of which was slightly downhill and would have been awesome at speed.
Well worth doing as a route. It took me just under two hours to do that loop and that was with a fair bit of walking and repairing. I hope to get back and do the whole loop again.
