Intervals today. I really had to drag myself out, but I felt like I had to go today if I'm going to get one more hard workout before my race. 1 minute hard run, 90 seconds walking recovery x 7. Unfortunately my HRM wasn't picking up, so I can't compare it to last week (running surface and ambient temperature were very different anyway). Felt pretty good though. 4.2 miles with warmup and recovery run.
