I don’t live in terrain that is conducive to training anything other than V02s on short power climbs, or on weekends when a main road is closed to traffic (But clogged with runners, walkers, cyclists, etc…) so I just do all my sustained intervals indoors (SST, threshold, most of the VO2 stuff). Honestly, I don’t even mind anymore - even on nice days. I have family stuff to contend with so any training is part of the process, and watching netflix is fine for me for long SST intervals.
I like to ride outdoors with friends and you can’t really do intervals with people of different FTPs than you. I either say “chill” pace meaning I’m trying to keep it zone 2, or it’s whatever goes. You don’t have to stuff outdoors if it doesn’t work for you.
