I’m no longer a 40-something, but I found them hard but manageable.
I’ve sacked them off now as I can’t be arsed doing intervals any more.

Not if the 120% is based on a reasonably accurate indoor ftp.

I'm a 40-something and have noticed that intervals above FTP seem disproportionately difficult.
Not TR, but at the moment I can manage ~265W avg over 45 mins without pushing myself into the red, so my FTP is presumably something around that. Anything >300W feels like hard work after 2 mins. Don't think I could do many intervals at 320, should probably give it a go.

Do any other 40-somethings find TrainerRoad Vo2 workouts involving 2-2.5 minutes at 120% impossible? Are they a young mans game?
