CM, if you don't have a copy of Freeman's Peak When It Counts, let me know and I'll send you my copy. I got a used one at Igy's suggestion, but now that I have a coach I don't need it. Plus, it's too complicated!
This new trainer of mine is great. My wife and I are able to use the same gear on the bike, she doing the slow pedal and I working up to a fairly brisk rpm. The trainer adds resistance like magic. I go in on sprints 2-3 times in a session and there's always enough pushback to keep me grinding away.

If I try really hard, I can maybe feel something sore where my injury was. But I'm in no hurry to get back to running. I finish each ride in a dripping sweat, all caught up with my Premier League highlights. I know it's not the same as pounding the pavement, but I'm safe from COVID and running injuries. And when it's time to start up again, I see how I could increase my active time to 14 or 15 hours a week without killing myself.
I guess that's a brag too, Mopac. I'm lucky to be able to do this.
