OK, I know I'll get all kinds of different responses here, but maybe there will be a central theme...

I have my first century of the season in 2 weeks (Mar 12). My knees are killing me, on and off the bike (though more off the bike than on...this is a new thing for me with cycling. My knees are why I had to quit running ). I'm tinkering (tiny tinkers, nothing drastic) with the bike, trying to see if anything makes a difference. I figure I have one more week of "hard" training and then I was planning on a bit of a taper the second week. So do I:

1) Back way off until the pain is completely gone and risk losing conditioning at this (critical) point? Note that I would probably continue my resistance (weight) training.
2) Continue to ride (the trainer mostly) short rides, keeping the heart rate on target (no intervals or anything)?
3) Stick with my normal routine, which is to ride through it (and go buy a new bottle of Vitamin I)?

(Note that in any case I will continue to ice/stretch, so that's a given.)

Thus far I've been riding through it and while it's not getting worse, it's also not getting better. Given my focus (and ability to work through pain), I doubt that the pain will keep me from finishing the C (which is my only goal at this point--no time goals or anything) and I don't think I'm doing any major damage...my skin just hurts mostly. Frankly, it's messing with my head (why this? and why now?), which makes me cranky.

Thanks,
