Had to cross quite a lot of open moorland today (including -
naturally - four river valleys, three of them taking me
rapidly from 200m+ down to not much above sea level and
back again). The valleys were very pleasant, with a
strongish but manageable wind. Up on top I was blowing
around like a leaf! Took a scenic route home, but refrained
from going up the track to Princetown (at over 400m) - which
would have been a normal version of that route.

Pork Hill (Princetown to Tavistock) is the best road descent. Ever.
Someone from St Budeaux CC claimed to have hit 72mph down there; I got
up to 56mph but then caught up with a car!!!
