Jason Fitzgerald is one of the best known and best regarded running coaches online. As the founder of Strength Running, he is an expert in strength training for runners, injury prevention, overcoming plateaus, and longevity.
Today we have a pretty wide-ranging conversation about strength training and running, including why it’s so important for runners, how to get started, what the minimum effective dose looks like, Jason’s tips for injury prevention and overcoming performance plateaus, as well as sports science and what he’s learned in the past 10 years.

In today’s episode, Brady and Thomas walk through 30 of the most popular running metrics - whether it's weekly volume, cadence, HRV, or VO2 Max - discuss the merit of each one and attempt to sort them into three buckets: Optimize, Track, or Ignore! We also discuss the deluge of metrics in recent years, how to separate signal from noise, why some of the best metrics can't be measured by a wearable - and we both pick a if-you-could-choose-only-one metric...

In this episode, Brady and Thomas do a deep-dive on post-run nutrition, exploring the 4Rs framework and how they (and their audience) can apply it to their running routines.
Review paper: The 4Rs framework of Sports Nutrition:
https://www.mdpi.com/2075-1729/15/6/867
The 4Rs app:

00:00 4Rs Framework Intro
03:30 Allostatis explained
06:00 THE 4Rs FRAMEWORK
06:06 1st R - Rehydration
11:10 2nd R - Refuel
17:44 3rd R - Repair
21:58 4th R - Recovery
25:43 - Applying The 4Rs - Brady's Practices
29:50 - Thomas' Messy Approach
34:44 - Applying the toolkit to busy lives
37:27 The 4Rs app
39:01 Why The 4R framework is so useful
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.
