[yes, I realize some of you have come to this same conclusion already, but I'm still deep in denial.]
Looking at my training last week, I can't help thinking that it looks like 10K training, not half-marathon training (stupid knee):
Tue: 4 miles "steady run"
Thu: 4 miles "easy run"
Fri: 2.2 miles "tempo run" aka "redemption run"
Sat: 5 miles "long run"
Saturday's run was wholly on dirt and my knee was okay. I purposely dialed back on distance to give my knee some recovery time. At the end, I felt like I could go farther. I toyed with the idea of adding extra distance, but I figured it was good to quit while I was ahead for a change.
Next week I'm going to try to run 7. If that doesn't work out for my knee, I may need to seriously reconsider what I'm training for. Perhaps instead of training for a half-mary I should actually be training for a 10K.
While poking around on active.com, I conveniently found a 10K in April on a relatively flat surface. Sounds like the setting for a new PR perhaps? Hmmmm. Thinking about it. Ducks aren't all bad.
