Thanks all.
Ended up just doing a couple of road rides. Friday was pretty straightforwards from Llandegla to Betws. I’d planned to go up via Brenig but a bit of a GPS fail meant a more direct route.
Saturday was a complete wash out. Got a soaking going round Penmachno and was in no mood to head back out on the road bike.
Sunday ride was from Betws, along the A5 to Bethesda, across to Llanberis, then up Pen y Pass and back via Capel Curig (linky). I did consider a route back through Beddgelert but had rubbish legs that day 🙁 so much so I was pleased that Pen y Pass was nice and steady without any nasty ramps!
Would be nice to go back and do some proper road riding in that area. Riding down the Ogwen Valley past Tryfan with the clouds rolling over the mountains makes you feel pretty small!
