In this podcast clip, Peter Defty sits down with Scott and Abby Jenkins to explore the real-world impact of Vespa on endurance performance. Scott, an experienced ultra-runner, had long struggled with nausea, vomiting, energy crashes, and mood swings during the opening stages of big races.

Despite experimenting with countless fueling strategies—from liquid nutrition to gels to solid foods—nothing seemed to work.

That changed when his coach Jeff Browning introduced him to Vespa. The shift was immediate and profound. Not only did Scott’s stomach stabilize, but his energy, clarity, and consistency transformed. What was once an unpredictable rollercoaster transformed into consistent and sustainable performance.

Abby, who has crewed Scott through some of the most grueling ultras—including Cocodona, Badwater, and the Destination Trail races—saw the change firsthand. For years, crewing was a constant battle of troubleshooting: Scott coming into aid stations sick, depleted, and mentally foggy. With Vespa, she noticed the difference right away: Scott arrived more composed, decisive, and able to clearly communicate what he needed. For the crew, this was a game-changer, making their role more efficient and far less draining.

Peter highlights how fat adaptation and Vespa complement each other by reducing dependence on glucose, stabilizing mood, and giving athletes the mental clarity to stay sharp deep into a race. Scott now approaches ultras with a new confidence—not just in his legs, but in his fueling plan.

📌 Conclusion

Scott and Abby’s story shows how a simple shift in fueling via fat can completely transform the racing and crewing experience. With Vespa, Scott gained consistency, clarity, and resilience, while Abby gained the ability to crew more effectively. Their journey underscores the power of VESPA—not just for performance, but for the mental and emotional demands of ultra-endurance.
