Cyclinguphill says of this climb “It is a really tough climb, with 25% hairpins at the bottom, taking you out of the village of Porlock. After this very hard 1st mile, the gradient mercifully eases off, but it’s still a long drag to the top. It is a really tough climb. Porlock up the A39 is probably the hardest and steepest A road in England. It is a really testing climb. Very steep from the bottom, then a long way to the top. I rode up the hard way after the race up the toll road.”  Read more.
