If you have access to Facebook, you might want to drop in on:
Cambridge Kite Club - Power Kiters
https://www.facebook.com/groups/307074582645387/
This is how they describe themselves:
"We are face book based and meet up most Sundays based in Cambridge UK and usually go power kiting buggy at Newmarket heath most Sundays"
Newmarket Heath appears to be approx 20 mi/32 km from Cambridge center.
