Taper Week Intervals

Today I headed to the MIT track to do 5x1000 intervals.  I ended up doing 4x1000s because I was late for a meeting - but my right knee has an acute pain which i'm having trouble shaking - so I figure dropping the whole session was in the cards - and 4x1000 is ok.  I'm going to monitor the knee and see how it feels Wednesday - but I may give it rest until Thursday and skip this weeks tempo.  Would rather make the start line a little undertrained than miss this damn race.
