Good mention for the 18 week 55-70 plan ES & Tom13. That is a plan that works for a lot of people. My plan is kind of home made but it sort of ticks most of the boxes in that plan in terms of frequency, paces and mileage .... although I tend to lean more towards the 20 milers and sacrifice the odd hard run from it. btw ES that New York time you got is comparable to sub2.50 at VLM. You made a decent improvement in one campaign which I am envious of. I'm at NY later this year and realize that I need to work hard to produce a good run there, it's a more challenging course than VLM (I've heard). May tap you up for some info later in the year.
