Join host Peter Defty for an inspiring conversation with elite OFM athletes Bree Lambert-Sanders and Joe Sanders, two masters-level competitors proving that peak endurance performance doesn’t end at 40—or 50. Bree shares her breakthrough season, including top finishes at UTMB-CCC and Kodiak 100K, while Joe brings decades of competitive insight and the science-backed wisdom of fat-based fueling. This episode dives into metabolic efficiency, stress, recovery, longevity, and how Vespa + OFM help athletes perform at their best at any age. A must-listen for ultrarunners, triathletes, and anyone curious about optimizing human performance.

What happens when elite endurance meets smart fueling? In this episode, ultrarunner Scott Jenkins and his wife and crew chief Abby Jenkins join Peter Defty to share the story behind Scott’s breakthrough performance at the Arizona Monster 300—a 300-mile race that became a personal best, thanks to Vespa and fat-adaptation.

Abby gives a candid look at the emotional and logistical demands of crewing ultra-distance events, from managing nutrition meltdowns to dealing with hallucinations in the desert. But everything changed when Scott began using Vespa, resulting in stable energy, better mental clarity, and smoother aid station stops.

🎧 Inside this episode:

How Vespa helped Scott overcome nausea and maintain pace

Peter Defty and Andrea Moore get together to discuss shattering boundaries in human health & performance. In early May Andrea completed the Cocodona 250, while a month  earlier she completed the inaugural edition of the Arizona Monster 300. Completing both became known as “Monsterdona” with only 6-7 athletes able to complete both of these grueling trail ultras. But the adventure does not end there. As this podcasts drops for public consumption Andrea is finishing up the Tahoe 200 and has plans for another 5 200+ mile trail ultras this season.

In Episode #77 of the OFM podcast, Peter Defty welcomes Dr. Amy Bukszpan, a behavioral analyst and endurance coach, to explore how applied behavioral science can empower athletes to take control of their nutrition, performance, and daily decisions. From breaking carb addictions to reframing failure, they dive into how modifying environmental variables and cultivating curiosity over fear can dramatically improve outcomes both in and outside of competitions. This conversation bridges cutting-edge metabolic performance with real-world psychology for anyone ready to take their performance—and life—to the next level.

OFM Podcast Host, Peter Defty sits down with Dr. Johnathan Edwards MD for an in depth and candid conversation on the underlying reality of sports nutrition. With the current hype surrounding high carbohydrate diets and fueling regimens which are dominating the conversation in sports nutrition this is a conversation every athlete needs to listen to inform their journey so they can achieve “Higher Health & Peak Performance”.

Colin’s powerful transformation from an unhealthy lifestyle to becoming an elite age-group triathlete (all while balancing a demanding career, coaching, and family) underscore the importance of performance level metabolic health. 

OFM confers metabolic efficiency by building metabolic capacity. Combined with strategic carbohydrate fueling, Colin has unlocked winning performance without compromising health and longevity. 

His journey proves that endurance success isn’t predicated upon high-carb fueling—it's about optimizing fat metabolism to establish a robust metabolic foundation then building upon it with strategic nutrition choices. Whether you're a competitive athlete or simply looking to improve your performance, Colin's insights provide a game-changing perspective on fueling for performance and lifelong health.

Phil Maffetone and Peter Defty provide a masterclass in optimizing health and performance by reconnecting with our evolutionary biology by challenging the myths propagated by modern corporate interests.

Episode Summary

John shares his incredible experiences as an elite cyclist, Marine Corps F-18 fighter pilot, ultrarunner, IronMan Triathlete then coming back full circle to his first love of cycling culminating most recently with Badlands. 

John was an early, early adopter of OFM beginning in 2010 by first using VESPA. Like so many people pursuing endurance sports John was suffering from GI issues and bonking. While VESPA made a huge difference in John’s fueling, his full adoption of OFM in the fall of 2010 has had profound long term benefits which are part of the conversation. 

Key Highlights:

Discussion Topics:

This episode showcases the transformative power of OFM for endurance athletes over the long term. John Rutherford’s journey . . . 

. . . highlights how OFM supports a person to consistently show up and be the best version of themselves no matter what the challenges of ultra-endurance events, including Life! Remember, along with being the Foreign Service Officer for the US Department of State assigned to NATO (John reports directly to the US Ambassador to NATO &  he is fluent in Russian), John has a wife and two boys. 

Hopefully John’s long term OFM journey will inspire you to reassess whether the conventional wisdom of high carb dieting and fueling (which is, essentially, “too much sugar”) and whether it really makes sense while exploring how the OFM program and protocols offer a roadmap back to your native physiology and in alignment with our evolutionary heritage. 

Doesn’t matter whether you're an elite athlete, age grouper or simply looking to be the best version of yourself in all aspects of life, John’s journey there are nuggets to glean for everyone including how to enjoy the ride, because, remember, whether you know it or not we are all signed up for that ultra-endurance event called Life! 

Peter Defty sits down with recently retired elite ultra runner, Jenny Capel, to reflect on her 22-year journey in the sport, much of it fueled by VESPA and OFM. Jenny shares personal stories about her father, Roland Martin, an early ultra running pioneer, and how she initially found running to be "stupid" before becoming one of the sport’s top competitors.

Jenny discusses her transition from a reluctant runner to an elite athlete, and how OFM (Optimized Fat Metabolism) and Vespa played crucial roles in overcoming GI issues and achieving long-term success. She talks about the importance of balancing life as a mother, physical therapist, and competitive runner, highlighting her decision to scale back from racing to start a family all while maintaining her love for the sport.

Key topics covered include:

Jenny’s Early Introduction to Ultra Running and Reluctant Start

• Jenny’s father, Roland Martin, was an early ultra running pioneer, competing alongside some of the sport’s founding figures, such as Gordy Ainsleigh, Bruce LaBelle, Wayne Miles, Dana Gard and Bill Finkbeiner..

How OFM has helped Jenny navigate Female Health

• At 51 Jenny is showing none of the signs of perimenopause symptoms.

Embracing Life After Racing and Continuing to Run for Fun

• Jenny still runs regularly but focuses on enjoying the process, often exploring new trails and embarking on adventure runs without the pressure of competition.
