Scruffychimp- Al is right, go out by the Gog Magog hills and Wandlebury and you will find some rolling hills. I used to ride the Roman road all the time as well on my fixed gear beater bike! It runs behind the golf course there, and connects to the back of Wandlebury. Has the added benefit of being the most beautiful little area near Cambridge on account of the hills.

Al, Great photos, Very inspiring mate.... cant wait to read more!

Take care.
