Running 1:30:00 [2] 20.13 km (4:28 / km) +3m 4:28 / km
shoes: NB 1080
90’ outside, mixture of ploughed trails, hard pack snow tracks and road. Orders were first 60 below 150, last 30 just below 160. Starting to get used to sticking to HR. Interesting to see how much a change in 10 beats alters my breathing and pace.
