The climb starts innocuously enough through the village, past houses and up a steepish slope - nothing too brutal though, but still healthy enough to get me breathing hard.The road calming measures that Simon mentioned were just paint/rough lines on the road - they gave you a bit of a judder as you went over them, but weren't too bad.
I remembered to turn left at the junction (I hate it when you have to do turns on a climb as the paranoia that you have gone wrong is massive) and enjoyed a flattish section, before it got hard again and you can hear me clicking through the gears to find one that I could climb up.The road ramped up to 19% and rose straight ahead of me for a bit - I had the classic front wheel lifting when I was in the saddle so again, I was in and out just to keep the legs working hard. The road was pretty narrow, but when a car came the other way, he very kindly pulled over and let me go through.
Just before the cattle grid, you can hear my phone ringing. Entirely reasonably, I ignored it as I remembered that after the cattle grid there was going to be a steep left hand turn and the gradient would ramp up. It was at 20% approaching the corner and going round it, the gradient bit in and caused my legs some pain (apologies for the bellowing as I went round!)The cloud hadn't lifted unfortunately, so we were unable to get really good views going down - but it was pretty special even with the cloud present. Took my mind off the painful climb anyway! A little flat stretch then preceded the final effort to the top - which you could see clearly stretching in front of you.
A nice, tough climb and a good way to round off the Wales hills.
