Just do them way easier. Like 50% of FTP.
But that’s not fast enough for Strava 
I made good experiences with this. But yes - super slow, especially uphill (difficult to comply with, my FTP is low compared to some here) and I live in a hilly region. Also 80km take forever 
in any case I feel much better during and after riding.
One thing I try and get across to people I ride with or coach, who cares how fast you’re going on training rides?? But there are those out there who literally won’t ride with you if you won’t maintain 20mph average on your ride. It’s so dumb… time in the saddle is what matters, not how far you go.
Exactly, I am even doing all workouts (both intervals and LSD) on gravel bike with 38mm tires, to resist any competitive urge 
I am more on the side of „TT bike with skinsuit“ to compensate for my low FTP and IF.
Joking, gravel bike is super comfortable.
Nobody cares, but the one of hallmarks of improvement after several years of hard work is when your Z2 is fast! 
Yep, agree. Just can’t always force it when you are building to high volume. I think it’s one of those things that just kinda has to come around with time. Endurance pace when riding 10h/wk is going to be different than endurance pace when moving up to riding 20h/wk for a while for a lot of people.
The people I’m thinking of specifically (some locals) aren’t riding “zone 2”. It’s your typical every ride is too hard type Crew.
