Running intervals 48:17 8.59 km (5:37 / km)
ahr:145 max:183 shoes: R-NB-Gray-460 # 3
VO2max intervals, exceeding that speed on one or two due to Keith (who'd run 100 miles 3 days before) joining in ahead of us all...
600: (target 2:06-2:12) 2:11 , 2:10
800: (target 2:48-2:56) 2:55, 2:51, 2:46
600: 2:03, 1:53
Unfortunately, this seemed to cause a R-hamstring injury - that I solidified with a 5k race 3 days later... oops.
