The Endurance Lab

Most runners think about training in terms of mileage, intervals, and long runs. Very few think about heat as a performance tool. But heat training could be one of the most accessible and evidence-based performance levers available to any recreational runner — and it requires no extra miles, no gym membership, and no expensive equipment. In this episode Dr. Daniel Snape — sports scientist, environ...

Patrick Wilson is an exercise physiologist, sports nutrition researcher, and author of The Athlete's Gut. He has spent his career studying how the gut responds to food, fluid, and supplements during exercise — and what actually works versus what the industry wants you to believe. In this episode Patrick breaks down the optimal carbohydrate intake per hour based on the actual dose response research...

She is one of the most decorated American distance runners of all time. But what made her great was not just her training. It was what she did with the six inches above her shoulders. In this e...

Everyone seems to be chasing 120 grams of carbs per hour at the moment. But the research says that performance actually starts to dip after 100 grams per hour. And the fuelling plan behind two UTMB wins proves it. Paul Booth is a sports nutritionist, exercise physiologist, and lead nutritionist for the Salomon International Team with 26 years in university academia and 92 ultras completed himself....

In this episode we cover what his new paper actually claims about muscle glycogen versus blood glucose, why he now believes 120 grams of carbs per hour works — and why the mechanism is not what anyone thought, the difference between fueling your metabolism and stimulating your brain, why recreational runners may be unknowingly developing pre-diabetes, the central governor theory updated, and his s...

In this episode Matt breaks down exactly why recreational runners become their own ceiling, what he learned training alongside professional runners half his age in Flagstaff, why the 80/20 rule does not need to change as you get older, the carbohydrate debate that is dividing the endurance world right now, and the psychological edge that separates athletes who reach their potential from those who...

Most runners think getting injured comes down to weak glutes, bad form, or worn out shoes. But physiotherapist Brody Sharp says the real reason is almost always something else entirely — and most runners over 40 are missing it completely. In this episode, Brody breaks down the load versus capacity model that explains 90% of running injuries, why strong and weak runners get injured at exactly the s...

Most runners train to improve their lactate threshold. But what if improving it is actually making you slower? In this episode, I sit down with Dr. Peter Tran — sports medicine PhD, 1:14 half marathoner, and co-founder of Athyx — to break down everything runners over 40 need to know about lactate, how to actually use it to guide training, and why most of what you've heard about lactate threshold t...

We talk about the real reasons behind her longevity in running: consistent mileage, simple training, smart...

Andrea Moore is one of the most accomplished ultra runners in the sport, completing eight races over 200 miles in just eight months in 2025. In this conversation, we explore what it really takes to race at the edge of endurance, from 100 milers to 200+ mile ultras, and how fueling, fat adaptation, recovery, mindset, and durability all change as the distances get longer. Andrea shares how her appro...

Most runners track HRV, but very few actually know how to use it correctly.

Can your breathing be the hidden reason running feels harder than it should? In this episode of The Endurance Lab, I sit down with Dr. Andrew Sellars to explore one of the most overlooked performance limiters in endurance sport: breathing. Most runners focus on aerobic fitness, mileage, and strength training — but almost nobody trains the muscles that power every breath. Dr. Sellars explains how i...
