Jim Walmsley: 4x Western States Champion

Jim Walmsley discovered Neversecond through his own research, drawn to the brand’s science-first approach and precision fueling system used by elite cyclists. After testing the products himself, he quietly adopted Neversecond ahead of his historic 2023 UTMB win—where controlled, gut-friendly fueling made the difference. That success laid the foundation for a long-term partnership built on mutual respect and a shared commitment to high performance. Today, Jim continues to collaborate closely with Neversecond, helping shape the future of fueling in ultrarunning.

I was finally able to get my fueling under control at UTMB this year using Neversecond. I was able to hold down 60g of carbs per hour which really helped me in the last 50km.
