A change to the 2012 Cheshire Cat route (102 mile version) has been made.
The map below (click to enlarge) shows the original route in purple and the new route in yellow.
Much of it is the same, but the section in the West http://hesca.net/valium/ shows some very distinct changes.
The official event page is here. Make sure you grab the new gpx file if you’re using it to navigate.
