I will e-mail those of you who have asked. tommo, I have sent you a message.
What richwales says is true, and I have never met anyone on that ride that wasn’t supremely decent. In fact, their policy was always to ride only as fast as the slowest guy, and to stop for beer and food at the end.
The only thing is, as someone who would only just be returning to riding in the dark, and not being very fit at that, I would not want to be the one holding them up. I figure if I go out again a number of time and get my confidence up, I will make it to Tongwynlais on a Wednesday sometime by spring…
