I think doing 10K everyday is brilliant but would sugest that you get outside and run as it feels alot different running on the roads than on a treadmill. If you want to do the marathon then go for it, follow a training plan like Shiva suggests and you won't be last - that would be me! Good luck and have fun!
I've still not got round to entering this yet. I really struggled in the London mara and my confidence has taken a nose dive. I'm only doing runs of about 3 miles at the moment (mostly with my dog). I did the time delay thing on website and came over quite queasy! lol
Stubee - that's awful , there are too many idiots in this world, hope you are ok.
