The Running Explained Podcast

In this solo episode, I'm FINALLY tackling one of the most important (and least sexy) topics in training: training load. What it is? Why should you care? And how can you make sure you're living in the "juuuuuuust right" zone!

Most of us are so focused on paces and mileage (or kms) targets that we miss the bigger picture: how much stress your body is actually experiencing and accumulating from your training. And if you’re stuck in a cycle of “train hard → crash → repeat,” this episode is especially for you.

I break down everything from acute vs. chronic training load, to how wearable devices, like your Coros running watch, calculate your load using things like "TRIMP" and heart rate, and to how to use heart rate variability (HRV) as a recovery gauge. We’re talking spreadsheets, ratios, metrics, and yes: how your “just right” is totally different than someone else’s!

• What training load actually means (and what it doesn’t)

• How to avoid the dangers of "too much too soon" (even if your mileage says you should be OK)

• Why intensity (and training intensity distribution) is more important than distance alone

• How the acute:chronic ratio of your training load tells you when you’re on the onramp to the highway to the danger zone

• What the 10% “rule” misses (and why it’s not always that simple!)

• The difference between “I ran 10 miles!” and “I worked HARD for 10 miles!”

• Tools like TRIMP, TSS, and HRV: what they tell you and how I use them

• The deets on my own quick & dirty training load spreadsheet before I had fancy tools

• Why managing training load is especially important for self-coached runners!!

  
  

TOP SOUNDBITES:

“Your body doesn’t track distance; it tracks stress.”

“That hero week you’re so proud of? It might be the reason you need a nap for the next 10 days.”

“This is about learning what ‘just right’ looks like for you—because too much breaks you, and too little stalls you.”

What would happen if you decided to just… run around the world?

No, seriously. That’s what Marie Leautey did. She’s only the second woman in history to complete a verified World Run—crossing four continents, coast to coast, on foot. She pushed a stroller (not with a baby - important note), slept in a tent, dodged kangaroos, used bear spray in Montana, and somehow didn’t get injured while running over 28,000 kilometers.

In this episode, Marie and I talk about:

• How a random doodle at work turned into a 2.5-year global running adventure

• What actually counts as a “run around the world” (yes, there are rules! No, they don't make you run on water!)

• Staying injury-free while running 700+ marathons in a row (the “body scan” trick is genius)

• The joy of running without pace goal… or time goals… or really any data at all

• Being mistaken for a mom with a baby in a stroller (and how that probably kept her safe)

• Why she got fined $2,600 over a rogue scallion at the Australian border

• And how to tell the difference between giving up… and just hitting a (global pandemic) Pause Button

Marie’s story is one of those rare ones that’s impossible to summarize and even harder to forget. It’s about running, yes, but also freedom, persistence, problem-solving, and learning how to really listen to your body (and your gut).

📖 Her book Lootie’s World Run: The Extraordinary True Story of the Fastest Woman to Have Run Around the World is wonderful; part memoir, part field guide, part “wait, she did what?!” Get your copy today!

This week I’m joined by Jeff Horowitz—"recovering attorney" turned running coach, author of Think Like a Runner, and someone who’s run over 200 marathons (yes, really!). Jeff shares stories from his global racing adventures (including an ultramarathon in Cairo where he was chased by wild dog s), his journey back from a devastating femur fracture, and why he thinks every runner—no matter their pace—deserves to take themselves seriously.

We get into:

• Why so many runners struggle to call themselves runners

• How your relationship with running evolves over time

• What it means to truly trust your body again after injury

• How to define success beyond speed or finish times

• Why you do deserve good gear, a coach, and the “serious runner” stuff, no matter your pace

This was one of those conversations that just felt like a long exhale. If you’ve ever questioned whether you’re a “real” runner, or wrestled with how to stay in love with this sport as things shift and change, this episode is for you

Let’s get back to basics! In this episode, I’m breaking down the three main types of runs you'll see in your training - easy runs, moderate-intensity workouts like tempo or threshold, and high-intensity speed work - and explaining what each one is actually supposed to do for your fitness. If you’ve ever wondered, “Am I running this right?”, this one’s for you.

Once you understand what each run is meant to accomplish, the next step is learning how to execute it correctly, and that’s where simple alerts on your running watch can be a game-changer. I’ll explain how I use pace and heart rate alerts to help build confidence, stay in the right zone, and most importantly, start enhancing our internal understanding of what those different intensities feel like. This is how you move from chasing numbers to actually training smarter.

🎉 I’m also incredibly excited to announce my official partnership with COROS, the running watch I’ve personally used and loved since 2022! COROS makes it so easy to set up the exact alerts I talk about in this episode. You don’t need to pre-program fancy workouts (although I love those too), just a few simple tools can help you train more effectively and confidently.

And now, when you use code RUNEXP at coros.com, you’ll get a free second strap with your watch purchase!

👟 In This Episode:

• What easy, tempo, and speed runs are designed to do

• How to use watch alerts to guide effort (not just chase paces)

• Why learning what effort feels like makes you a stronger, more confident runner

• The tools I use on my COROS Pace 3 watch to keep training dialed in

  Heart rate & pace alerts to create effort “guardrails”.

An ankle sprain can put a serious crimp in your style, especially when it happens two days before race day. In this episode, I’m joined by Dr. Lauren LaPierre, physical therapist, running coach, and trusted resource for all things injury rehab, to break down what it actually takes to recover from a sprained ankle and get back to running (properly!)

In this conversation, Lauren breaks down what a sprain actually is (yes, it’s more than “I rolled my ankle”), how to assess its severity, and why conservative care should almost always be your first move. She walks us through each stage of her own recovery, from using compression and regaining range of motion to eventually reintroducing running through careful, progressive loading. She also shares the mental and emotional toll of dealing with a derailed season and how to give yourself the grace and space to process it.

Whether you’re dealing with an acute injury, navigating the gray area between “healed” and “ready to run,” or simply want to understand how to support your future self (or athlete clients), this episode is packed with wisdom, relatability, and practical takeaways.

IN THIS EPISODE, YOU’LL HEAR ABOUT:

• The different grades of ankle sprains and what they actually mean

• How to handle the first 24–72 hours post-injury (and what to avoid)

• Why swelling and pain don’t always equal more damage

• How to use pain as a guide... without letting it become a barrier

• The critical rehab phases: isometrics, strength, neuromuscular control, and plyometrics

• The real timeline for returning to running safely

• Common mistakes runners make in trying to come back “too soon”

• The emotional weight of missed races, lost momentum, and re-setting goals
