Cannot cfm but then no pain at all.
Only thing is I cannot speed caused it's strained on my right ankle.
How about trying racewalking. 2-3k per day would do, that was what i did last time, good enough for the mind.
That is something in which at least 1 feet is touching the ground at all times, no flight time unlike running.
See if it helps.
It can help aerobically as well, neruomuscularly as well. Got movement, will do.
When i was racewalking for 2 years, the first time i transited to running (ie i never ran before for decades for middle/long distance) and did a TT round my rooftop of 1 round = 800mm, 2 rounds of 1.6k i stopwatched 6 mins 20 seconds.
That is a pace of 4:13, 2.4k equivalent of ~10:40. Not too shabby.
So it would benefit running one if that is one thing you love to do and dont wanna lose fitness. The last session you shared was a 10.78km run iirc, imo that is pretty long man.....and o understand your motivation to run but the thing has been dragging too long liao.
And our ages are more similar than different so at least this area we physiologically sama sama.
Then 3 months later, try running again.
Esp since cycling you dont wanna do.
