Just above Talybont Reservior near Brecon. Think the Cotswolds are flatter than that, the picture doesnt do it justice (or rather the cameraman who set up the camera ), it looks very flat there, but it drops away to nothing just out of sight, very steep.
The "new" bikes should hopefully be coming. Amanda's Carrara, although good for a beginner has shown its not up to the job really any more, so we are on the hunt for a couple of new bikes, off to test ride them this weekend
EDIT: Heres the route if you are interested - http://connect.garmin.com/activity/40181163
