Tempo running today 2x15 mins with 2 mins static recovery. Was hoping to keep hr below 170 bpm but with the heat and the undulating route found it practically impossible unless slowed right down. 1st 2.8km @ 5:20 min/km ave hr 169bpm max 174 bpm 2nd 2.65km @ 5:40 min/km ave hr 171 bpm max 175 bpm #running #temporunning #adidasrunning #runnersofmastodon
