If you''re bonkers enough to like hill running then try wendover woods... some of the lesser footpaths give gradients that vary from tough to vertical but the better trodden routes provide a more gentle challenge. You can park in the car park, run for as long as you like and get lost as often as you like but you''ll always find someone who can point you back to the cafe in the woods, where you can join the mountain bikers for a drink and a bite before heading home. Well worth a run.
