Cyclocross - CX and SSCX races and training

I reckon you might be okay with them. They're not ideal but they have good cornering grip, which is what you need at Somerhill. Most of the course is grassy, but the section from the top of the course to the bottom is where you need grip, a fast descent into a sweeping right hand corner, up the steep bank to the top, which is usually rideable if you get the corner right, then the series of banked bends where grip and technique is key.
