I knew I would forget something!
Here is the link to the membership form.
The only membership available now is the £15 non-affiliated membership as the window to join England Athletics has now closed.
The reason why we are asking for members only to join us on club runs at present is that we will have your details in case these are required for contact tracing. When we have test-run the sign-up process for runs for a few weeks, we will allow non-members to come and try us out before joining. Non-members will need to provide us with contact details before joining a run.
Any questions regarding this, please let me know.
