I’m trying my darndest to follow an 80/20 run plan but I’m struggling to stay in zone 2 for my easy runs. I can maintain a good easy pace with my HR in zone 2 for about 20-25 minutes but then it spikes into zone 3. In order to bring it back down I often have to walk or shuffle.
Should I slow down my pace way down when it is creeping up to maintain a slower HR? Or just keep the comfortable pace and go off of pace and perceived exertion and screw the HR if I’m feeling good. Or do I need to start way slower so it doesn’t creep up as much. I know sometimes my HR so also variable with my hydration status etc, so wondering if pace is a better indicator than HR.
Thanks so much!
