Talking Points

Recent interactions between the hosts and their guests.

The Proven Fueling Strategy Behind 2 UTMB Wins Applied to Your Next Race | Paul Booth
Q: Is there evidence that mouth rinsing with carbohydrate solutions can affect performance in long ultras?
There is some evidence suggesting a CNS stimulatory effect when glycogen is depleted, but the practical significance varies, and more recent research indicates the effect may occur regardless of glycogen state; the perceptual boost is not necessarily tied to a specific amount consumed.
The Proven Fueling Strategy Behind 2 UTMB Wins Applied to Your Next Race | Paul Booth
Q: What is the role of glucose-to-fructose ratio at higher intakes, and does it affect GI comfort or oxidation efficiency?
A mixed approach around 0.8 to 1.0 (glucose:fructose) tends to improve overall oxidation and gut comfort up to about 90 g/hour; beyond that, changing ratios can yield diminishing returns and may increase GI distress if pushed too high.
The Proven Fueling Strategy Behind 2 UTMB Wins Applied to Your Next Race | Paul Booth
Q: For recreational runners without access to a lab, what practical rule of thumb could they use to estimate their carb needs?
Start with a baseline around 60 g/hour, test gut tolerance on long runs, and build a buffer by exposing the gut to a little more in training than you plan to use in race conditions, while adjusting for pace, duration, and heat.
The Proven Fueling Strategy Behind 2 UTMB Wins Applied to Your Next Race | Paul Booth
Q: Can you walk me through what the testing looked like and what it told you that you couldn't know any other way?
Lab testing provided confidence and a data-driven basis for adjusting fueling; it revealed individual fat and carbohydrate oxidation rates, peak oxidation timing, and how race intensity would shape carbohydrate needs, allowing a personalized plan rather than relying on a generic 120 g/hour target.
HRV Expert: Most Runners Read HRV Wrong | Dr. Marco Altini
Q: How do aging and sex differences affect HRV interpretation?
HRV generally decreases with age and varies with sex due to hormonal differences; however, there is substantial individual variability, especially across menstrual cycles and menopause, so personal baselines are essential.
