Run science, explained.

This week we're exploring longevity for runners, and how running can potentially help us live longer.

Expect to hear about a sub 4-minute miler's life expectancy, why VO2 Max is the most important trait to optimize for longevity, and thinking in decades not years.

00:00 Intro

02:00 What we know about the science of longevity

05:34 How running could hurt your longevity (Coronary Artery Calcification)

12:30 ‘Outrunning the grim reaper’ study of 4-minute milers

20:11 Why VO2 Max is the most important trait for longevity

24:00 How much can you train your Vo2 Max?

28:24 Reliability of measuring VO2 Max

31:48 Training protocols for increasing VO2 Max

34:44 Training considerations for older runners

36:52 Developing a mindset for longevity in running

39:20 Going from goals to systems

44:45 Setting goals that can improve longevity

The traditional model of running physiology had 3 elements: VO2 max, lactate threshold, and running economy.

But in recent years, a 4th element has been brought to the table, 'physiological resilience', or durability.

Brady Holmer walks us through what it is, why it matters, how we can improve it, and why Kipchoge is the king of physiological resilience.

Thomas sits down with Brady Holmer, 2:26 marathoner and science writer, for a comprehensive conversation about all things Zone 2, and how runners can use Z2 in their training - while busting some myths along the way.
