I was sifting through the forum and found this gem. Now i hope i don't upset people, but i see lots of people full on keen and enthusiastic about starting something and seems like we all want to be presented with something, like "where do i sign up?".. and the posts can be some months apart so nothing has really taken off, which is not anyones fault. I think the best thing would be like what barby q is doing, just set a date, organise a run and do it, like the Nike ad suggests. It might be hard to organise a "group" like what has been suggested, but if people just set dates, organise and advertise it on here and JUST GO, the group will build. Even if no one turns up, don't let that stop you or put you off, get out and do it, don't wait for it to come to you. Then you get back and stick up photos and say how good it was and everyone gets jealous. If you get back and put up a trip report and whinge about how no one turned up and you never get any support or interest, you just put people off, so the problem compounds.
I hope no one sees that as a big whinge, just trying to be constructive
