A bit delayed posting this as these screenshots are from the end of March, but wanted to mention I’ve managed to build up a new streak again using my 75+75 approach. This really is giving me the flexibility I need (I will forever miss my long countryside runs though) and (according to Apple Health) it’s been enough to get my VO2 max almost back up to the levels it was at when I was doing marathons. So that’s nice.
The peaks in running are extra runs with A, otherwise I’m pretty level. Although my VO2 max is back up, my Strava fitness level is way down, but I don’t ever track any of my walking on there and there is a fair bit.
