Disappointment

It is now 4 days post-prolo and I am about 30% better than before the treatment. I no longer have a visible limp and can go down the stairs normally if a bit gingerly. That's well behind where I had hoped to be at this stage. I know that I can't run until the left knee feels the same as the non-injured right one. It's still a bit stiff when I walk and it hurts a bit to straighten it out. I initially thought that it was PFS (Runner's knee) but after some additional research, it is clear that the problem is quadriceps tendinitis. The tendon that attaches the lower part of the quads to the top of my knee is damaged. A website says that the average recovery time is 4-6 weeks and I feel that my case was more severe. Prolo will likely ultimately speed the healing process but Huntsville is looking like it will be downgraded from questionable to doubtful. It's now been 2 weeks and I am feeling the ill-effects of not running. I can feel that my dopamine is falling and I am beginning to get some muscle stiffness as well as low-grade depression. I sent in my hair sample and am hoping for the worst. The medical report will likely reveal what I can and cannot do as a runner in the future. Even before this injury, I had grown weary from the volume of marathon training and said that Boston would likely be my last one. Now, it is becoming increasingly clear that my dream of qualifying is dead. The race sold out within 8 hours of opening and now the BAA is likely to make the standards even tougher. I may need a 3:05 or even a 3:00 to qualify in the 30-34 age group and no worse than a 3:10 at 35-39. Very few people are capable of these times and I am pretty sure that I am not one of them.
I've considered quitting marathons altogether but have decided against it. However, my all out marathon training cycles are over. Odds are what will happen is that I will sign up for a half and plan on running it up until the last week of training but I reserve the right to switch to the full if my training goes exceptionally well. All I want is a sub-3:30 or less than 8 minute pace and when I do that, I swear that I'm done with marathons. I ran a 3:35 while dependent on pills so I have no reason to believe that I can't go 5 1/2 minutes faster when free. Also, I may be softening my marathon goal a great deal but my goals at the shorter distances remain the same.
400- 59.9
Mile: 5:15
5K: 19:12
10K- 40:00
Half- 1:30:00
2011 will be my first full year of freedom so let's go after those times.
If I am to quit marathons, I want it to be on MY terms, not dictated by any type of imbalance!
