Dont wanna stray too far from the original thread, but some words for fUrCeOsNhN.
You could be training too hard too regularly, based on what I see in the training schedules you put up so far.
Maybe for your curent comeback, and for the future, you might consider training way below what you might now perceive as optimally fatigued. Might be that you have unknowingly treid to include too many components in a regular week or cycle of training, in attempt to cover all training bases, and that acumulation of stress can lead to breakdown.
If you do hills primarily now as a transition back to full training, I hope you can control the volume and do far less than what you believe you need to reach your running goals. My observation is that you were already very fit before the setback, and by returning with less work (while maintaining the intensity of hard workouts), you will perform much better in the coming season.
Also I wonder if you feel that your easier days prior to injury might have still been too hard for optimal recovery? Or that maybe you ought to have had more easier days betwen hard days? This maybe considered even for now and for the future.
You seem to have a capacity to run a lot of hard workouts in a short frame of time, but your body's limitations differ too much from your lung's capacity.You sem to have a strong willpower for work and that's admirable but I feel with more restraint you can enjoy training more and race even better.
Could you still be doing the crosstraining too hard, too regularly? Hard rowing for 40 min 2x a day could be going toward overtraining again, in my opinion.
My advice is have more days when you feel 'normal' again, esp the days after hard workouts. If not you are either training too hard or too much or both, or you are not resting enough between workouts.
Its the difference betwen Kenny Moore and Steve Prefontaine. Both could train hard, but Moore needed more rest between hard days while Pre could hammer 2-3 hard sessions in a row with little or no recovery days between. But both are world class in their respective events and also Olympians. It doesn't really make one superior or inferior as athletes.
In my opinion, few should attempt more than 2 very demanding workouts a week, even when you include crosstraining, weights, plyometrics, short sprints, circuits, pilates, core work, etc. Unless each workout is low in volume relative to that runner's ability.
If my observations are misplaced please forgive me, but I think you have trouble holding back and should cut yourself some slack. Try a more laid back approach this time on and you will probably reach sub 2 or 1:50 soner than later.
