I don't visit the forum as often as I should 
I've dabbled in running, I am a member of a ladies only running club - most I've ever entered in for is a 10k - although completing the Preston Guild series which includes a half marathon next month! 10k tomorrow, 10 miler November, already done the 5k.
I'm a slow plodder runner and eariler in the year put a ballot entry in for the London marathon - no charity, no special cause etc, so assumed 99.9% chance of not getting in.
Well I now have a place! I'm bricking it. how do I train? What do I eat? More importantly, I need to book a hotel room now for next year, how do I find a reasonably priced room for me and my doubting husband and daughter.
Plus, I would only do it if I raised some money for charity - how do I decide which of the worthwhile causes that arrived with my pack do i do it for.
I am usually a normal, professional, rational person but this has thrown me.
I don't want a sub certain time, I just want to finish! 
Any help, advice, pointers etc would be greatly appreciated
Cheers!
