@crufit. Competitive. Alternate 250m @ "5sec above 2k pace, and then at 2kpace" Personal goal row 1:55 and 1:50. Immediately got frisky on the hard and drove down into the 1:47-8 range. Started slipping at about the 2.5k and the easyies suffered the most drifting towards but under 2:00 and the hards drifting towards 1:50. Big finish drove down into 1:40 range. HR at 500s: 152, 157, 157, 158, 159, 159, 159, 162. Definite maxed out at end. Really good piece considering current 5k max pace is 151.4.
