I’ve done the Challenge on several occasions, over the last 10 years (though last time was about 5 years ago now). It’s a brutal climb, never quite made it to the top, even when I was fit, it’s a tough bone and teeth shaking descent – especially the baby heads by Melgarve, and then a long road stretch.
I’ve pushed too hard and suffered severely, but it’s always been a great event, challenge if you like, great spirit of taking part and helping out, and I’ve made and met up with so many friends at that event. The reception at the end is superb.
Slicks changeover would be recommended – just swap whole wheels really. That or compromise tyres which work in the dry, but would be lethal in the wet.
Gavin, not like you to bonk 🙂
