Not quite a road century

I had intended to do a 100 mile road ride yesterday, but it didn't quite happen. Woke up ridiculously early, so I was on the bike at 6.30am, but it was a glorious morning and I was plenty warm enough with just a jersey, arm warmers and gillet. Rolled down to Llanberis, climbed up Pen y Pass in a rude head-wind, then down to Betws y Coed. Shortly after that the GPS batteries died (no, of course I didn't take spares). through Penmachno and past Llyn Celyn to a cafe stop just north of Bala. Then Trawsfynedd, Prenteg, Beddgelert, Penygroes.
The first 95 miles felt fine, the last 4 miles took 30 mins. Felt quite tired afterwards.
