so how do i register to do this ride?
Hello! Go to the blog
here, it'll tell you all you need to know.
Short version: You will need to email Simon with confirmation that you've read the basics (on the blog), your CTC number if you have one, and your mobile number. You will need to join our club, the Fridays (£1), and if you're not in the CTC you'll need to affiliate to it (£12) for insurance purposes (under the group third party policy, there's a maximum of five non-members per ride, I don't know if that's been reached for this one- and everyone must have third-party insurance via CTC, British Cycling or the London Cycling Campaign, even if you've got a policy of your own).
