Nice lengthy interview with the king of the 3 Peaks on the British Cycling website. This one's by Joolz Dymond. A good read.
I don't ride the Cyclo-Cross bike at all, unless I'm racing it. I just go on the road or turbo in the winter. It's too dark to get out there and give it some welly. I might try and take some time off next year and do at least one day a week in the light.
