Hi Paul,
I ran this one in the 1980s when it started & finished at the cricket ground, went into the city centre & out with a bit more variety to the same rural Chartham Downs area as always.
The last used route (May 2010) is a simplified, almost straight out & back route but with a loop for the outermost section. It started at the rugby ground & did not go into town.
Check out this web page from my Garmin site - not the actual event but a practice last year a week before Hastings. The route is exactly as for the last (2010) event.

Copy this to your browser address pane & I think the maps etc will now load on phones, iPads, etc without Flash as well as on computers.
Let me know if this works!
Tom
