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.

In this episode of the Singletrack Podcast, I chat with sport scientist and physiologist Geoff Burns to unpack one of the biggest open questions in trail running right now: why shoe technology hasn’t produced a single, decisive “Vaporfly moment” on the trails - and whether it ever will.

Geoff explains why trail running is fundamentally different from road running when it comes to performance gains. While road shoes can be optimized for straight-line efficiency on uniform surfaces, trail shoes operate in a far more complex system - one shaped by uneven terrain, gradients, stability demands, traction, weight, and constantly changing conditions 

Geoff explains:

* Why super-shoe logic breaks down on trails
* The real role of foams, plates, and energy return off-road
* Why shoe tech gains often disappear on uphill, downhill, or technical terrain
* Whether trail shoes are nearing saturation—or still wide open for innovation
* How weight, traction, durability, and stability compete with pure efficiency
* Why different trail races may require entirely different “optimal” shoes
* What shoe tech might be changing in the sport

What actually changed with David Roche’s YouTube content and why did it work when so many running vlogs and films don’t?

In this episode of the Singletrack Podcast, I’m joined by running filmmaker and YouTube creator Jeff Pelletier for a deep, behind-the-scenes conversation about how trail running content is evolving and what Roche’s Western States series revealed about the platform.

We break down why YouTube rewards long-term storytelling over one-off films, how stakes and failure can be more compelling than winning, and why personality-driven channels consistently outperform brand-owned media. Jeff explains why Roche’s rollout felt like a masterclass, how it changed expectations for branded content, and what brands, athletes, and creators still get wrong about YouTube.

We also discuss:

* Why most running brands fail on YouTube
* How narrative arcs and episodic structure drive retention
* The difference between short-form and long-form impact
* Why YouTube is becoming the new television for endurance sports
* What the next era of trail running media might look like

Our annual Ultrarunning Year in Review is here!

Topics include:

• The biggest ultrarunning storylines of 2025
• Breakout performances and unsung heroes
• The most dramatic races and moments of the year
• Comeback athletes and rookie standouts
• Surprising results that rewrote expectations
• The rise of agents, Substack, and athlete media
• Brand wins, sponsorship shifts, and product moments
• What 2025 tells us about the future of the sport

Thanks for tuning in! As always, this conversation is subjective, North American ultra-biased, and built for debate -  so we want to hear from you. What did we get right - and what did we miss? What moments defined 2025 for you?
