The head cold and a sore calf

Been taking it easy since Wednesday morning's hill run. Noticed my left calf was getting more sore as I ran, so I slowed way down the last 2 miles. That made it a little easier to skip my 6 mile tempo run Friday, but the main culprit was a head cold that started up, also on Wed. Friday was the worst so far...I needed the extra rest that morning. Still planning my 20 miler Sunday...calf seems better today.
