On today’s episode of RUNWITHALLI LIVE, I’m joined by a very special guest, Bill Armstrong, Founder & CEO of Neversecond™.

Founded in 2020, Neversecond™ has quickly become my go-to fueling brand and has firmly established itself within the endurance and high-performance running community. Neversecond™ is the official fuel sponsor for RunWithAlli Coaching, and I truly believe this product can change the way endurance athletes approach fueling for marathons and beyond. Especially for those pursuing competitive performance for the long haul.

Before discovering Neversecond™, I was genuinely frustrated with fueling. After years of high-volume training and racing, I had tried countless products that caused GI distress, felt inconsistent, or simply didn’t meet the demands of endurance sport. That all changed when a friend in San Diego introduced me to Neversecond™. From the very first trial, the approach clicked. Precision, simplicity, and science-backed execution. I immediately knew this was the kind of fueling system serious endurance athletes need, and the kind I wanted our athletes using.

In this episode, Bill and I dive into the evolution of the Neversecond™ brand and the philosophy behind it. We talk about how Neversecond™ supports endurance and high-performance athletes, what truly sets the brand apart from other fueling companies, how runners can practically apply these products in both training and racing, how to build community around fueling, and so much more.

Questions we cover include:

How did Neversecond™ come to life, and what gap in the endurance fueling space were you trying to solve?
What backgrounds did each of you bring to building the brand, science, sport, business, or all of the above?
Neversecond™ is known for precision fueling. What does that mean in practical terms for endurance athletes?
Can you explain the science behind products like the C30 gel in a way runners can immediately apply?
How early in a training cycle should athletes start practicing race fueling?
For someone training for their first marathon, what’s a simple Neversecond™ fueling framework to follow?
What lessons from elite sport translate best to everyday endurance runners?
If athletes could follow just one fueling principle, what should it be?
How do you decide which stores carry your product?
Why did you say YES to being on the RUNWITHALLI LIVE Podcast?

Whether you’re an endurance athlete, an aspiring runner, or simply curious about the space, I hope this episode leaves you feeling inspired, better educated on fueling for running, and more aware of the endurance fueling landscape, and how Neversecond™ can support your athletic and endurance goals!
