I know there are a lot of people planning to do half marathons/marathons/10ks/triathlons etc next year, maybe we could all cheer each other on and raise money for the same charity? It might encourage more people to get involved if there's an organised group of us and maybe MNHQ could help us promote it (if we suck up a bit).
That's about as far as I've got with the idea so far 
Anyone interested?
