Intensity Can a three-hour run reveal aerobic threshold? "Is it crude to use the average heart rate from a 3-hour run to roughly guesstimate aerobic threshold (AeT)?"
Aerobic Capacity For how long can aerobic capacity improve? "I've read that aerobic capacity building can go on for 6, 8 or 10 years, even for full-time athletes. And I recently read how Nils van der Poel spent ~30 hours/week for 3 years in building his aerobic base."
Intensity How does cooling down improve aerobic capacity? "What is the reason for cooling down after a workout? What are the consequences if we never cool down? Does the kind of workout matter? What does the ideal cool down look like?"
Intensity What metabolic information can we get from a flat half-marathon? "I've read that a time trial for 10k or 45 min or 1 hr is a general test for one's anaerobic threshold, and a marathon is raced at one's aerobic threshold. Is that true?"
