2.5 miles easy, 2.5 miles hard, medium reps

Ran to work in 17:46, average pace 7:13/mile, and back home in a new PB of 15:41, average pace 6:23/mile. The club session was 400m reps on the other side of Maryhill Road, starting at the roundabout and following the road round to the car park. Wore the Brooks Green Silence. After a 0.15-mile warm-up I ran 1:19, 1:18, 1:19, 1:18, 1:17, 1:17, 1:16, 1:18, 1:16, 1:13. Most of the reps came out as 0.26 miles. Max HR was recorded as 188, but that seems unlikely and 174 looks more accurate. Warm-down was 0.49 miles, total mileage for the evening 3.2.
