Old Horseshoe Pass loop

Arguably the most brutal road climb in north-east Wales, I wanted to incorporate it into a meaningful loop with OHP as the climax. I have run it before (at the end of a truncated Llangollen Round) and I've cycled up it (which is even harder). But this loop went from the Ponderosa to the top of Cyrn y Brain (9.58). Then across the always boggy plateau to join OD, before a long section on quiet roads to Pentredwr, girding the loins before the vicious climax up the 'Old Shoe'. It climbs over 700ft in a mile with almost no respite - despatched in a respectable 11.25 from Pentredwr to the Ponderosa.
