Bill Armstrong, co-founder of Neversecond, joins the show to break down one of the biggest shifts happening in endurance sports today… fueling.

For years, endurance athletes were told to take in minimal carbohydrates during training and racing. That approach shaped how runners fueled for decades. But as the sport has evolved, so has the understanding of how much fueling actually impacts performance.

In this episode, Steve Gonser sits down with Bill to unpack the full story behind Neversecond and the evolution of modern fueling strategies. From early misconceptions around carbohydrate intake to the breakthrough of multiple transportable carbohydrates, Bill explains how the science has progressed and why athletes are now fueling at levels once thought impossible.

The conversation goes beyond theory and into application. They discuss what happens physiologically when you underfuel, how fueling impacts performance late in races, and why consistency and precision matter more than most runners realize.

Bill also shares the origin of Neversecond, the gap he saw between research and real-world products, and how the company set out to build a system that athletes could trust and execute on race day.

If you’ve ever hit the wall, struggled to maintain pace late in a run, or felt unsure about how to fuel… this episode will give you a clearer framework to work from.

We recorded this episode at 5 a.m. to catch Ethan Shuley while he’s in Japan living and training.

Before running 2:07 and landing one of the top 10 fastest U.S. marathon times, Ethan’s start in the sport wasn’t what you’d expect. He talks through the early days of struggling to keep up, skipping races, and not enjoying running… and the moments that shifted his mindset.

In this conversation, we get into:

• His early experience with running and what almost pushed him away from the sport
• The turning point that changed how he approached training
• What his current setup looks like training in Japan
• How his perspective on effort, consistency, and competition evolved

This is a look at what actually shaped one of the fastest marathoners in the U.S. right now.

Running a 2:30 marathon while attending medical school is a rare balancing act. In this episode, Steve Gonser sits down with Elle Orie to explore the path from multi-sport athlete in Orchard Park, New York, to Cornell distance runner, Colorado steeplechaser, and emerging elite marathoner. Gabrielle reflects on her late start in competitive running, her development through collegiate track and cross country, and how a strong aerobic base from swimming shaped her endurance progression.

The conversation also dives into the realities of pursuing elite-level performance while managing the demands of medical training. Elle discusses waking up at 3 a.m. for runs during clinical rotations, building toward 100-mile weeks, and the emotional swing of missing the Olympic Trials standard by just 11 seconds before breaking through with a 2:30 marathon at the Chevron Houston Marathon. Along the way, she shares lessons on fueling, recovery pacing, staying healthy, and keeping the sport fun even while chasing world-class goals.
