Legwork is a podcast that celebrates the unseen efforts that keep the sport of running moving forward. We go behind the scenes with club leaders, race directors, and running community organizers to uncover the work that keeps us on the roads and trails. We talk to coaches to understand the evolving science of how we train, and we recognize the effort built into all the miles that come before we lace up for the starting line. What matters isn’t always visible. Explore what lies beyond the shortcuts.Bakline Running ランニング・ジョギング

    14 - Does music make you run better?
    2026/06/19
    A practical look at how music affects running performance, from cadence and perceived effort to mood, motivation, and the messy science behind your favorite pump song.Narrative SummaryA playlist can feel like a secret weapon, a pacer, a distraction, or a trap. One song can settle you down. Another can make you surge too early. A beat can pull your stride into rhythm without you realizing it.Matt, Molly, and Alex explore the strange and useful space where music meets running: not just as motivation, but as something that can influence cadence, effort, mood, and movement. They look at what the research can tell us, where it falls short, and why the most important variable might still be the person wearing the headphones.The answer is not as clean as “music makes you run faster.” The more interesting answer is that the right song, at the right rhythm, for the right runner, might help you move better, feel better, or hang on a little longer.Episode DescriptionIn this episode of Legwork, Matt and Molly are joined by Alex of the Allie G Show to explore how music affects running performance. They start with the songs that get them moving, then dig into what the research says about cadence, perceived effort, mood, motivation, efficiency, and the role music can play when running starts to get hard.Together, they cover:How runners use music differently for workouts, races, long runs, and late-race survivalWhy tempo, beat strength, volume, familiarity, and personal preference all matterHow music can influence cadence, rhythm, and movement synchronizationWhat rate of perceived exertion means, and why music may make the same effort feel easierThe difference between music as motivation, music as distraction, and music as a pacing toolWhy self-selected music often matters more than a generic pump-up songWhat studies on music and running performance actually show, and where the research gets messyWhy treadmill studies, small sample sizes, short testing windows, and hard-to-blind designs limit what we can confidently sayHow runners might use music strategically without becoming dependent on itAlong the way, they talk about Harry Styles, movie soundtracks, pop punk eras, metronomes, race playlists, groovability, and the danger of over-optimizing something that is supposed to help you enjoy the run.Whether you race with headphones, save music for mile 20, use it to survive the treadmill, or prefer to run with nothing but your own thoughts, this episode will help you understand what music can and cannot do for your running.Chapters00:00 Introduction and personal pump song selections by Matt, Molly, and Alex10:35 High-level buckets of scientific impact music has on performance13:49 Variables in music that have been studied as potentially impacting running performance20:45 Additional thoughts on future research directions and musical elements not covered in studies29:45 The impact of music on cadence36:01 Understanding rate of perceived exertion, heart rate, and mood41:48 Metrics and methods that were not as commonly assessed, plus reactions to findings45:21 Limitations of music studies in sports and additional questions that could have been asked55:25 The impact of music on performance in numbers01:05:11 Key learnings from music and exercise studies01:09:37 Interesting observations from studies on how music impacts performance that may not have practical use01:19:02 Personal reflections on music in running, and whether Matt, Molly, or Alex will incorporate any findings in their own runningSongs referenced:Scatman by Scatman JohnAs it Was by Harry StylesI'm Shipping Up to Boston by Dropkick MurphysWe Take Care Of Our Own by Bruce SpringsteenNo Time For Caution (Interstellar) by Hanz ZimmerSk8er Boi by Avril LavigneEvery Little Thing She Does Is Magic by The PoliceFire and Rain by James Taylor

    13 - The Science and Art of the Negative Split: Bank Energy, Not Time
    2026/05/07

    A deep dive into the physiology, psychology, and pacing science behind negative splitting in track and road racing, and why the fastest times are often run by athletes willing to start slower to finish stronger.

    Episode Description:

    It’s one of running’s oldest pieces of advice and one of its least trusted: don’t go out too fast. Yet every race morning, thousands of runners surge through the opening miles convinced they’ve somehow escaped physiology. The pace feels easy. The crowds are loud. The legs are fresh. Until they aren’t.

    In this episode of Legwork, Matt and Molly unpack why the negative split remains one of the most effective and misunderstood strategies in endurance racing. Using Matt’s Boston Marathon breakthrough as a launching point, they explore the science of pacing, glycogen depletion, lactate production, thermoregulation, muscle fiber recruitment, and why “banking time” so often turns into borrowing against a debt the body eventually collects.

    The conversation moves from elite marathon racing to practical pacing mistakes recreational runners make every weekend. They examine why even slight pacing errors early in a race can create cascading physiological consequences later, why going out too fast feels deceptively easy, and why the body’s warning signals in the final miles are often less about “mental weakness” and more about real biological limits being reached.

    At the center of the episode is one core idea: don’t bank time, bank energy.

    Together, they cover:

    • What a negative split actually is, and why it’s more than simply “starting conservative”
    • Why elite marathoners and championship fields overwhelmingly negative split to win
    • The science of glycogen depletion, fat metabolism, lactate, and endurance energy systems
    • Why running slightly too fast early creates disproportionate fatigue later
    • The misunderstood relationship between lactate, “lactic acid,” and muscle fatigue
    • How heat accumulation and cardiovascular drift quietly sabotage races
    • Why Boston Marathon pacing strategies often fail
    • The psychological reasons runners still go out too fast despite knowing better
    • How progression runs and marathon pace workouts train athletes to finish stronger
    • Why negative splitting creates more control, confidence, and resilience late in races
    • The difference between surviving the final miles and still being able to race them

    Along the way, Matt and Molly, compare pacing strategy to maximizing an electric car’s battery range, reflect on the emotional side of racing, and explain why passing people at mile 24 might be one of the best feelings in the sport: ultimate confidence that you puled it off.

    Whether you’re training for your first half marathon, chasing a marathon PR, trying to break a major time barrier, or simply tired of fading in the final miles, this episode offers a practical and science-backed framework for pacing smarter and racing stronger.

    Bonus 3: What You Need To Know To Run The Boston Marathon—and Why It’s Harder Than It Looks
    2026/04/17

    A practical course strategy for Boston that covers race-day logistics, pacing, hills, and fueling, so you don’t give your race away before Heartbreak Hill.

    The Boston Marathon itself doesn’t test how fit you are. It tests how well you understand what you’re stepping into. It tests how well you can plan and prepare.

    The course gives you just enough early to make you believe you’re having a great day. Downhills feel free. The pace comes easily. And somewhere between Hopkinton and Wellesley, it’s all too easy to lose sight of the fact that you might be borrowing energy from later you.

    AIn this episide, youll learn to understand why Boston is hard, how to approach it with intention, and when to hold back even when everything feels right.

    Boston isn’t about surviving the hills. It’s about arriving at them with something left.

    Episode Description

    In this joint episode of the Allie G Show and Legwork, Alex, Matt, and Molly break down how to approach the Boston Marathon from start to finish with three primary sections: race day logistics, a section-by-section course strategy and analysis, and race week and day nutrition and fueling.

    Drawing on their own experiences across multiple Boston races, they explain why the course is more tactical than it looks—and how small decisions early in the race can shape the final 10K.

    Together, they cover:

    • How to plan race weekend logistics, including the expo, transportation, and starting village
    • What makes the Boston course deceptively difficult despite being “net downhill”
    • How to pace the early miles so you don’t give back time later
    • A section-by-section breakdown of the course, including the Wellesley tunnel, Newton Hills, Heartbreak Hill, and the Citgo Sign
    • Why Boston rewards restraint early and patience through the middle miles
    • Common mistakes runners make in the first 16 miles—and how to avoid them
    • How to think about fueling, hydration, and carb loading for race week and race day
    • Adjusting your strategy based on weather, effort, and how the day unfolds, and
    • What to expect in the final miles and how to close the race strong

    Along the way, they share lessons from past races, including pacing mistakes, fueling issues, and what it actually feels like when the race turns.

    Whether it’s your first Boston or you’re trying to run it better than last time, this episode gives you a clear framework for approaching the course with intention.
