Totally agree on average speed, if I manage 10mph average I'm happy.
I'll take a look at my GPS plots and post some details on good climbs, won't be tonight though.
Hazel Wood down to The Weighbridge is a great twisty singletrack, but you need to ride it a few times to discover which route you like.
The trail fairies have build a rough bridge over the stream bed which is superb at speed in the dry …. but deadly in the wet. I've done a two wheel slide ( wheels out sideways ) on slippery timber straight off the bridge edge which is embarrasing.
Further down you have the choice of the open route to the right of the stream or down the stream. The gate at the road is always closed, which is just as well.
If you really like a tough climb try it uphill….
If you like strong coffee ask Paddy in The Olive Tree for coffee with 5 shots, that's how I take mine and it is excellent. They have their own blend of coffe and it is very good.
There are many routes up Spring Hill rather than straight up, the one I like is via The Village Inn, then The Britannia, up the Rollers and join the hill half way up. Rather depends where you are heading from there.
