I'm curious to know how many years it may take to improve my fitness to run a marathon in 2:55. I didn't start running until after college. I've been running for about 10 years, but consistently only the past two years. This resulted in a 3:08 marathon last spring, and a 3:03 marathon last month. 3:08 was done on about 55 mpw. 3:03 I got up to 65-70mpw. If I consistently run 70-80mpw, how long would it take to get to 2:55 or even 2:45? 1-2 years? Or is it even possible? Is more mileage needed to get there? If so, how do I get there and how long will it take? Would it make more sense to train for a fast 10k or half and see how that translates into a faster full? Sorry lots of questions, thanks in advance.
there is no set equation for mileage vs performance.
you definitely have the ability to run well under 3 hours if you ran 3:03 on 65-70 mpw. Just repeating the training you did before, or extending it for more weeks, will make you run faster.
The biggest thing to think about is monthly or annual mileage. You need to be training consistently year-round to make big improvements. So you've run a couple 70 mile weeks. Well, imagine how fit you'd get if you averaged 65 mpw for 10 weeks. that's what gets you the fitness...not the biggest single week.
As for the actual workouts...it's much less important than people assume. Just find some people who are a little faster than you and do the workouts they do, for company. Tempo? sure. Intervals? sure. just be flexible and try to do about 2 workouts per week.
