In response to hammer-head. Do you really think Gebreselassie hammers every run as hard has he can? I actually wondered this myself until I settled my inner controversy with Lydiards phrase, "train don't strain." After spending a month with a few of the top racers in the world, I found out what Lydiard really meant. Many morning runs, the pace would be exaustingly slow. One morning, one of the S. Africans even made a joke about it and started walking while we continued to run. Of course, other mornings were at a quicker pace, but none raised the heartrate above the threshold level. I asked why our runs would be so slow in the morning, and was told that the runs were to help recover from the harder runs during the week - including 3 track workouts of speed and speed endurance (20*400's in 65 (race pace) or 5*2000 in 5:30 for example). Now Gebreselassie might run quick relative to what our perception of "quick" is, but I can bet his heartrate stays in a "recovery" zone. Until you are at his level, you can't train by using his exact schedule.
Look at Lydiards schedules - a perfect layout of his entire plan is at

. For your everyday runs/recovery runs etc., a good measure to go by is keeping your heartrate under 160bmp. You can even start out lower and work your way up to this in the beginning part of your run. I would like to say one thing. I don't think Geb would be where he is today if he just went out a hammered every run anaerobically. He has trained smart, and it's this misconception that get's many kids to only run on the track, thinking every run has to be very intense. Hope this helps. sorry for making it so long.
