There will almost cetainly be a 'K' ride tomorrow. Even if the weather is bad there's always a few folk out. Just get yourself to the Square just before 10am and make sure you set off with the 'K' group and not the 'A' ride. Both groups set off at similar times but they usually announce which group is which (think 'A' might set off first but don't quote me on that).
As a paid up member you get a weekly email detailing the routes. This is usually sent out on a Thursday or Friday, but as yet i haven't received this weeks email, so I can't let you know the route. It'll probably be around 60-70 miles with a cafe stop half way.
Yes Stewy, I thought Kev might send you off with the A group. The secret is to keep a low profile and quietly latch onto the back of the K group, 5 miles up the road when he realises you're there it's too late for him to send you off with the hitters.
