Available on Spotify, Apple Podcasts, and all major podcast platforms, Science Of Ultra has earned its place as one of the most essential ultra running science resources in the endurance world. In this deep-dive profile, we'll explore what makes this show special, who's behind it, and why it belongs in your regular podcast rotation.
Meet the Host: The Voice Behind the Microphone
Dr. Shawn Bearden is an exercise physiologist and professor who brings genuine scientific rigor to the world of ultra running. An ultra runner himself, he bridges the gap between academic research and practical application in a way that's accessible to everyday athletes.
This combination of credibility and passion is what sets Science Of Ultra apart from the countless endurance podcasts that launch every year. The host brings genuine expertise to every conversation, whether they're interviewing a world champion or breaking down the nuances of trail running training for a dedicated age-group athlete. You can hear the difference between someone reading training advice from a script and someone who has lived it — and Science Of Ultra delivers the latter in every episode.
The authenticity shows in the questions asked, the training concepts discussed, and the practical takeaways that listeners consistently praise. When an episode covers ultramarathon nutrition, you know the advice comes from real experience, not theory alone. This credibility has helped the podcast build a loyal community of athletes who trust the show's guidance with their training, racing, and recovery decisions.
What You'll Learn: Topics and Themes That Matter
Science Of Ultra covers a wide range of essential endurance topics, including ultra marathon physiology, trail running science, endurance nutrition research, heat adaptation and acclimatization, altitude training, muscle damage and recovery, sleep deprivation effects, hydration science, and the biomechanics of running 50K, 100K, and 100-mile distances. The show's content library represents a comprehensive education in endurance sports — the kind of knowledge that used to require hiring a personal coach or attending expensive clinics.
Each episode is thoughtfully structured to deliver maximum value in minimum time. Rather than meandering conversations that bury useful information, Science Of Ultra gets to the point quickly while maintaining the depth that serious athletes demand. Topics are chosen based on what endurance athletes actually need, not what generates the most downloads — and that commitment to substance has paid off with a deeply engaged listener base.
- Training Methodology: Episodes regularly explore periodization, threshold training, base building, and race-specific preparation strategies that listeners can implement immediately in their own programs.
- Race Strategy and Execution: From IRONMAN race-day nutrition protocols to marathon pacing strategies, the show delivers actionable race-day intelligence for events at every distance.
- Recovery and Longevity: Understanding that endurance is a lifelong pursuit, episodes cover recovery techniques, injury prevention, and sustainable training approaches that keep athletes healthy for decades.
- Nutrition and Fueling: With endurance nutrition science evolving rapidly, the show stays current on fueling strategies, hydration protocols, and the latest supplement research relevant to endurance science athletes.
- Mental Performance: The psychological demands of endurance racing receive dedicated coverage, including visualization techniques, dealing with race-day anxiety, and building the mental resilience required for events lasting hours or days.
Standout Content: What Makes This Show Essential Listening
While every episode of Science Of Ultra delivers value, certain content areas have become signature strengths that keep listeners coming back week after week. Here are the themes and episode types that truly set this podcast apart in the crowded ultra marathon podcast landscape:
Episodes breaking down the latest exercise science research specifically relevant to ultra running
The show excels at episodes breaking down the latest exercise science research specifically relevant to ultra running. These episodes consistently rank among the most downloaded and most shared in the show's catalog, and for good reason — they deliver insights you simply can't find elsewhere. Whether it's unpacking the training philosophy of an IRONMAN World Championship contender or exploring the science behind altitude training, these conversations give listeners a genuine competitive edge in their own racing and training.
Nutrition science episodes covering fueling strategies for events lasting 12-36+ hours
Another pillar of the show is nutrition science episodes covering fueling strategies for events lasting 12-36+ hours. In a world of information overload, having a trusted source that distills complex training science into clear, actionable steps is invaluable. Listeners report making real changes to their training — adjusting paces, modifying nutrition, rethinking recovery — based directly on what they've learned from these episodes. That's the mark of a truly impactful ultra running science.
Heat and altitude acclimatization protocols backed by research and practical experience
The podcast also shines when it comes to heat and altitude acclimatization protocols backed by research and practical experience. These episodes serve as a virtual coaching session, giving listeners the confidence and knowledge to make better decisions about their endurance pursuits. From selecting the right goal race to understanding how to peak for a key event, this content has helped thousands of athletes approach their endurance journey with greater clarity and purpose.
Physiological explanations of what happens to the body during 100-mile races
Finally, physiological explanations of what happens to the body during 100-mile races represents another reason why Science Of Ultra has maintained its position as a top-tier endurance podcast. These segments resonate deeply with the endurance community, addressing the questions and challenges that athletes face every day. The depth of coverage and the quality of insights consistently exceed what you'd find in a quick internet search or social media post.
Who Should Listen: Finding Your Fit
Science Of Ultra is ideal for ultra runners and trail runners who want evidence-based guidance — athletes preparing for 50K, 50-mile, 100K, and 100-mile events like Western States, UTMB, Leadville, and Hardrock who want to understand the science behind their training. If that describes you — or if you aspire to become that athlete — this podcast should be a regular part of your training routine.
Specifically, you'll get the most from this show if you:
- Train for endurance events and want science-backed guidance rather than generic motivation
- Enjoy long-form content that respects your intelligence and treats training as a serious pursuit

- Are looking for a ultra marathon podcast that delivers consistent, high-quality content episode after episode
The show manages to serve both experienced athletes looking for performance optimization and newer athletes seeking foundational knowledge. This broad appeal without sacrificing depth is a rare achievement in endurance media, and it's one of the reasons Science Of Ultra has sustained its audience growth over time.

The production values match the quality of the content — clean audio, professional editing, and a pace that respects the listener's time while allowing for the depth that complex endurance topics require.
The show's consistency is worth highlighting.
