Assuming you haven't done any distance running over 2 miles in say, 2 years? I'm living in New York now and thinking of entering the NYC marathon in november 2006. The running info I have read all say you need at least 18 weeks, preferrably more to get in marathon shape, but they all assume you have distance running experience. I haven't done any running, aside from the occasional weekend run of 2 miles at most, in over 2 years. Even then the most I ran in an official timed event was a 2 mile race, which I did in about 13 minutes. Aside from CC in high school I've never really done much of any long distance running. Not worrying about time (short of finishing by the time they stop recording finishes at 6:40pm) could I realistically train myself to finish the race without serious injury and without burning out after 10 miles? I could care less about how I did, I think the experience itself would just be incredible; I just don't know if I could go from practically no running (doing a 5k without walking would probably leave me practically dead at the finish right now) to a marathon in 54 weeks.
