Off-Track Intervals

Today I did my first set of 'off-track' intervals at lunch: 5x4 minutes (~1K/interval). The average pace per interval was 6:44 (6:30, 6:30, 6:45, 6:45 and 7:09 - the last one was, as always, uphill). I'm doing well so far. I felt ok during the run, although my left calf was sore at the beginning. After the workout I felt a little sick, but coffee seems to have helped. Tomorrow is an easy 45 minutes out at Bluff Point.
