On October 18th (Sunday) there is the Caythorpe Chase which is a 28 mile loop from Caythorpe Playing Field. Mixture of track, field-edge, quiet lanes. Not a race and not technical or particularly hilly (with one notable exception if they keep the same route as last year). Pretty exposed for large stretches so wind and weather matter.
The entry fee is £10 (£12 on the day) and plenty of cake is provided. Entry form here: www.granthamtri.co.uk/Entry_Forms/TheCa ... se2009.pdf
Caythorpe is near to Grantham so kind of shared by the East Mids and Lincolnshire Groups. Seems a good excuse to get together.
