So yes, guilty as charged, I jumped on the marathon bandwagon. But now I want to change my focus. I barely had a base at those distances when I ran them, too. I feel I can improve greatly on these times. I would like some feedback on how to tailor a program that can build off of what I already have.
Any advice is appreciated.
Focus on simply running more. When your mileage gets quite high, start adding double workouts. Do most of your running at a comfortable pace. If you're beat, just jog it. If you're feeling good, hammer.
