> IMO there is no need to run any harder than that if your goal is maximising your wellbeing (unless your wellbeing comes from winning races...) Interestingly the best (or second best) bike racer in the world, Tadej Pogačar, is very big into "zone 2" training, in which the idea is you optimize your aerobic engine by spending the majority of your training time in zone 2 and no faster. While the zone 2 can be measured formerly with a lot of fancy equipment that monitors the gases you breath out and levels of lactic acid in your blood, the casual guideline for finding your zone 2 is a workout at the level where you can just barely hold a conversation while doing it. The casual definition of zone 1 is you can easily hold a conversation, zone 3 is you can say a few words but can't hold a conversation, and zone 4 is you are breathing so hard you can barely talk. So basically, even if your wellbeing does come from winning races, zone 2 training might also be the best thing to do (at least for the majority of your workout times).
