Malmo,
This summer I built to 50 miles a week from 34 using SOM. I recently did a time trial and ran 5:25! I have had 2 speed endurance workouts this far and I ran 4:57 last spring. This is about the same time I posted last year at our time trial. Why is this? How long before I regain my speed and start running somewhat decen times?
Oh btw I had no one to pace me on this time trial.
I don't know the specifics of what you're doing but simply saying "I did SOM" doesn't really tell me much. Most people who say they did SOM didn't really do it, they merely did what they thought it to be.
SOM is in-between season training to get you ready for the real cross country training in the fall, without physical or mental burnout.
With that said, going from 34 mpw to 50 mpw alone you should show improvement over the Summer, by virtue of cumulative aerobic development and (especially) physical maturity.
Give me your email address so that I can see exactly what you did this Summer and perhaps I'll be able to comment on it. I don't know what "(2) speed endurance workouts" means? it doesn't really sound like you've actually done SOM?
To answer your question in the title, building base is a continuous process. You get the benefits of base both immediately and at some point in the future. The problem here is that a lot of young runners understand base as something that happens in phases. Their thinking is "I do base now, for some point down the line." Frequently some point down the line never comes because of it. They don't think of it as a continuous process.
I've seen threads here where guys say that they've been injured in March or April, so they're going to skip the rest of their track season and concentrate on "building base" for the fall. That's a complete waste of the immediate. Running is a competitive sport. In sports everything isn't ideal. You play the hand you are dealt, not the ones that you want. Get in the game and play...NOW. Worry about the future in the future.
