Tips

Dragon Ride

August 27, 2020

This climb appears minor in the grand scheme of things, but underestimate it at your peril.

Once you’ve negotiated the junctions in Glynneath the road bends right then rears up to disappear into the cover of trees where, with the last house behind you the reasonably busy road, lined with thick foliage either side, settles into its solid 6% gradient.

Heading in a direct straight line there’s no let up in the degree of the slope, nor in the amount of trees that obscure the view you are working so hard to enjoy. At roughly half distance there’s a left hand kink in the road and you enter the next long straight that will take you to the summit.

Ahead almost the entirety of the remainder of the climb is in view which gives you an idea of the work needed but could also be a hefty psychological blow.
