A few discussions have been had around the varying HR values, really highlighting the dangers of reading too much into one-stop-shop methodologies around zones and the like.
Here’s my activity from Weds night - all sub threshold and i could’ve held on for another hour at least, probably more if the legs were up for it. https://www.strava.com/activities/2464027312#
I’m genuinely intrigued as to what i could achieve at Jorgan’s HR avg of his long run yesterday or the day before. During my, erm, recovery period in the next few days i might go out and see what pace i can get up to for 5-10km in the 120’s! Just as a (super) scientific experiment.
So also just a general warning for any newcomers looking to delve into HR based training for the first time. No matter how many books a particular author may have sold, or what pros they have coached, they odn’t know your body! Take the time to find works for you!!!
