I think I'm becoming wiser. :) I had planned 2 recovery runs yesterday after my mega workout Sunday-Monday (8k PR race, then 20 miler). My knee started hurting 0.5 mile into my recovery yesterday. Ordinarily I would have toughed it out. This time I shut myself down for the day! Today, no knee pain!! I wanted to run 10 miles through the Newton Hills. But, reassessed my taper schedule for Big Sur. I decided it is too aggressive. The worst case is to go into one of the most challenging marathons overtrained or injured rather than maybe loosing a little fitness. So, I got on the treadmill and did a moderate aerobic progressive run - that way I can shut it down immediately if I have any pain. I started at 8:27 min/mi pace, dropped the pace 0.1 MPH, until the last half mile which was at 7:51 min/mi pace. My knee was pain free!! I finished up with some weights, PT, and core work. I've had this issue with my other knee before, and 2x had to get MRIs, stop running for 1-2 months and go to PT. It has confounded all the people I have worked with. It's on my inner knee and it feels like a band is super tight and sometimes snaps over something. I think it's a result of an imbalance - a super tight adductor in combination with weak/tired glute med and poor glute med firing. What helps is: shutting it down if it's acting up on a run, massaging the attachment of the adductor to the pelvis, and glute med work to wake those puppies up to start firing again. It makes sense my megaworkout would cause this. I think I pushed to the limits and backed off just in time!!! :) |
