Combe isn't the best place for a 1st track day.
1st off, it's a bloody fast circuit with very little run off areas.
There are also no garages, there are no "groups" so a novice will be riding with advanced riders. (Turning into the chicane before Camp and having someone pass you doing twice your speed is very unnerving) and the noise restrictions are ridiculous.
The only redeeming things are: It's close and the food is pretty good.
