Not a mbswindon club event, but a must-do for all local mountain bikers and for a worthy cause, Macmillan Cancer Support.
Ride report from 2010 Castles event.
See their website for more information: http://www.castlesbikeride.co.uk/
This year MBSwindon have been asked to ride the route after the main event to make sure that there are no stray or injured riders on the route. If you would like to volunteer to do this then contact tom at mbswindon dot co uk.
