Hello everyone, first time posting here as I'm at my wits end trying to get my body to respond to training the way it should. In a nutshell - I raced the Ragnar Relay (3x legs of 8miles each, 1000+ feet elevation change per leg) about 6 weeks ago during my aerobic periodisation phase, had to take about 2 weeks for my muscles to recover - much longer than I anticipated. However, I did this through walking, very slow jogging, and generally just getting my body to respond.
The problem now is that I simply can't get my body to run as I did in pre-race form, even just for training. Where I used to be able to do long runs at a 7m clip I'm now dieing doing them at 8min.
I have been keeping a fairly detailed training log that you can see the dramatic drop off here:
Overtraining. I don't know anything about your background or your training prior to what is on your spreadsheet. According to what you've provided, you went from 20 miles per week to mid 50s in about 6 weeks. I've never seen a reputable coach, book or training plan that would recommend that kind of increase. Also you appear to spend too much time running too close to your race pace. You're racing at about 6:50 and you consider 7:40 an "easy" pace. Pick up a book like Daniels Running Formula (Jack Daniels) (there are other, equally worthwhile books) or read through the Running University section here http://www.mcmillanrunning.com/ to help design a better training plan.
