It is simply not enough to go out and run with your tunes in your ears and try to block out the pain. If you truly want to set a high goal and gun for it, you must own the pain in training. Push yourself on every other run if you are running everyday. To run a sub 3:20 marathon or what ever your Boston Marathon Qualifying time would be, you need feel the pain in training. There are no if-ocks and-ocks or but-ocks about it.
When I was in my mid thirties I could run races in pain the whole way. Somewhere along the line the Ipod came out and the desire to run guts out went away. Now I have taken on 4 training partners and the Ipod has stayed home. We are able to push each other and that feeling of running through the pain is coming back. I still run 3 times a week alone to push myself mentally and physically without the boost of outside assistance.
With the revived desire, a Boston Qualifying time is only a spring 2011 marathon away.
