Event has been rescheduled for 7th April.
I recieved this email:
"The elements have been much kinder since the weekend of the 24th March. Thanks to the fantastic support and cooperation of the Forestry Commission, the Highways Agency, St John Ambulance, the Forest of Dean Motor Club, and an army of volunteers - without whom this event would be impossible - we can now announce the date of the rescheduled event. All runners registered for the Forest of Dean Spring Trails Half Marathon are still registered with the same race number. We look forward to seeing you on the new, post-Easter, race day! If you really can't make it on the 7th April, check the web site for some options.
