Hi all. Thank you for “Training for the New Alpinism” and the ressources on the Uphill athlete website. They were very usefull to me last year to achieve my goals: a couple of short trails (20k), and passing the entry exam for the French International Mountain leader award (Accompagnateur en Moyenne Montagne).
My question is in the title: Fasted workouts, how long is too long?
During my training last year, I gradually switched my outings from afternoon to early morning, fasted workouts. After a while, I would easily run 10-12k sometimes a bit more, fasted (between 1hr and 1hr1/2) several times a week. I would make sure I had some food for longer outings, whether hiking or running
I hear some people say we shouldn’t go over 1 hour without food. But I don’t recall reading anything about that in the book or on the website. So, as I start building up the mileage again, how long can I go without food? Is there a limit to how long we should go?
