Assuming it's the same route as last year try the website at www.kilotogo.com/cheshirecat.htm seems to have various pages to look at. Just click onto map of route. Doesn't look very clear though,but might give you a rough idea.Hope it helps.
I didn't do the event this year as much of it is my normal training routes and I'm unwilling to pay to ride the roads I do every few weeks anyway
(- it's different doing an event somewhere new)
But a friend was keen to do it and to recce it first, so we rode the route out from Warrington rather than Knutsford, in two halves on two separate weekends - each was a decent distance including the out-and-back to get onto the route.
The routesheets on the Kilotogo website were easy to follow, although of course I knew most of the roads, but not necessarily their names...
