Searched all around for this topic and couldn’t find anything. I know you guys mentioned on an episode last year about pros going on fasted rides for like 5 hours. I’ve done some and heard somewhere that 90 minutes was either a min or a max time to go for.
By fasted, I’m referring to nothing for breakfast and going out on an endurance/“fat max” ride where you’re staying below aerobic/carb based energy sources.
What’s the shortest time that would be beneficial? Is there a max as long as you aren’t bonking?
