Tempo running this evening, 1500m warm up, 5k at tempo and 1500m cool down. The plan was to try and keep heart rate bordering hr zones 3 and 4 for the workout but allowing a little extra for any hills I had to negotiate so pleased with the results: 5km in 25:52 min, average pace 5:11 min/km, average hr 169bpm #running #temporun #5ktempo #polarrunning #runnersofmastodon #therunningcommunity #oldguysrule #dreadlockrunner
