I'm looking to do some hill intervals but can't seem to find any decent hills around Croydon.
I don't really want to go any further than about 4-5 miles from where I live at Park Hill cos my evening time is limited and i'd want to do a 15-20 mile round trip.
I've tried Croham Road, Shirley Hills Road, Ballards way but the gradients aren't that steep.
Any ideas?
