Organised by the same folks who do the Farnham Cycle Challenge that a few forumites did in May. 5k, 10k, HM options - so plenty to choose from.
Looks hilly - thinking of doing the 10k or the HM as practice - trying to start early to make sure the vicious run in Poland next year doesn't catch me by surprise...
Any takers?
