The excellent & very friendly local cycling club, Kings Cliffe Flyers, are holding their weekly (every Tuesday ko 7pm) 10m TT as an open event this Saturday the 9th July. As such it is a qualifier for the district championships.
If you've not done it & fancy a local, straightforward (i.e. quiet roads but not THAT fast; there are corners!) event, this is a really good one to try.
Check out the KCFCC website (http://www.kingscliffeflyers.org.uk) for more details.
