Singletrack

In this episode of the Singletrack Podcast, I sit down with Andy Blow, CEO and founder of Precision Fuel & Hydration, for a wide-ranging conversation about what athletes at all levels still get wrong about fueling and hydration in ultrarunning. 

A note up front: Precision Fuel & Hydration is a major partner of the Singletrack Podcast — a partnership we’re proud of and want to fully disclose. That said, this conversation isn’t contractually obligated. It’s the exact discussion I would want to have with Andy regardless, driven by a growing curiosity around nutrition, technology, and performance in endurance sports.

Andy brings a deep and unique background to the conversation, with a degree in Sports & Exercise Science from the University of Bath, experience working as a sports scientist with Formula 1 teams, and a role helping establish the Porsche Human Performance Centre before founding Precision Fuel & Hydration.

We explore both fundamentals and frontiers, including:
Why many ultrarunners — including elite athletes — succeed despite gaps in nutrition knowledge
Core hydration concepts like sweat rate, sweat sodium concentration, and blood volume contraction
The danger of chasing marginal gains before mastering the basics
Why real-time sweat tech still isn’t quite ready for prime time
 “Ballpark accuracy” vs perfect precision in fueling and hydration
Aid-station decision-making, guardrails, and crew strategy in ultra races
The emerging challenges of fueling and hydrating for multi-day events
I learned a lot in this one, and hope you do too.

In this annual State of Singletrack episode, Finn Melanson sits down with longtime collaborator Scott Hickenlooper to reflect on where Singletrack has been, what defined 2025 from multiple angles, and how the business, media projects, and personal priorities are evolving heading into 2026.

The conversation covers why the State of Singletrack format exists, how Finn thinks about transparency and building in public, and what listening habits and creative influences shaped the show over the past year. Finn looks back on the biggest accomplishments of 2025, including the release of Singletrack’s first feature-length film The Finisher and the launch of Twisted Fork Trail Festival, while also addressing where things fell short, from missed product ideas to community initiatives that never fully materialized.

The episode examines the realities of building a trail running media company, including the fragility of sponsorship-driven business models, how partnerships are structured, and why diversification through events and race coverage has become essential. Finn and Scott also discuss the growth of Singletrack’s YouTube channel, the challenges of sustaining that momentum, and open questions around future video projects and personal storytelling.

Looking ahead, Finn shares what excites him most about 2026, including Jules Campanelli joining Singletrack full-time, upcoming race directing responsibilities, coverage plans for major events, and his own racing focus on Scout Mountain 100 and the Bear 100.

The episode closes with audience questions, reflections on how Finn’s perspective on the sport has changed, advice for aspiring creators and athletes, and a look at dream interviews that remain at the top of the wish list.
