This year, you will have from Oct 1st until Nov 1st to ride the route. You can also start / finish from any point along it. Should your attempt prove successful, then simply email a gps trace of your ride to claim your badge.
I fully appreciate that it's quite unlike the previous 9 years but under the circumstances it's perhaps a reasonable compromise. The good news is that we'll have an all new route and the crafty will be able to pick whatever weather window may present itself.

Anyway, entries will open on Sep 1st - Sep 25th, route will be sent out Sep 26th and it'll cost you £15. No limit to number of entrants.
