Want a better year without burning out? Zoë and TJ share a practical, five-step blueprint to use your transition season to set up your best race year—without quitting running or living in the gray zone. You’ll learn how to keep frequency high (with easy intensity), sketch a long-range plan (1–3 A-races, smart tune-ups), match workouts to the right phase, and treat recovery like training so adaptations actually happen. We also tackle Hot-or-Not topics trail runners ask about: super shoes on road workouts, whether a shoe “quiver” really prevents injuries, and the truth about fueling with olive oil or swapping gels for candy. (Short version: practice what you’ll race with, and don’t copy Kilian.) If you’re planning a 50K, 100K, or 100M, you’ll hear when “real/solid” foods can help and why gut training matters. Subscribe for evidence-based coaching you can actually use.

Ever wonder what the difference really is between tempo, steady state, and threshold runs? In this episode of the MicroCast, coaches Zoë and TJ break down the most confusing middle zones in running, and explain how to use them intentionally to build endurance, speed, and confidence.

🎙️ You’ll learn:

• How to identify and feel steady state, tempo, and threshold efforts

• What’s happening physiologically at each intensity

• Common training mistakes (like running all your easy runs too hard)

• How to apply these workouts in your next training cycle

• Why effort-based training helps you avoid burnout and improve consistency

If treadmill season makes you question your fitness — you’re not alone. This week, Coach Zoë and TJ dig into why treadmill running often feels harder than road or trail running, and how to actually use it to your advantage. They’ll unpack the biomechanics, heat buildup, and calibration quirks that make treadmills deceptively tough — and how to dial in effort-based training so you get real aerobic gains (without chasing meaningless numbers).

Then they dive into adaptogens — what the science really says about ashwagandha, rhodiola, and all those “stress-busting” mushroom blends — and what actually works for performance and recovery.

You’ll walk away with a five-part recovery framework that prioritizes sleep, fueling, and nervous-system regulation over gadgets and gimmicks.

Plus: we’re kicking off our Run Your Best Marathon at Boston webinar series — four sessions that walk you through pacing, fueling, taper, and race-day execution with detailed tools and pro-level insight. Whether you’re running Boston or any spring marathon, this series will help you show up calm, confident, and ready to crush it.

🔥 Want to get more out of your training? This episode breaks down the five most important ways to nail your workouts—whether you’re training for a marathon, ultramarathon, or just building consistency. We talk pacing, mindset, and how to avoid the common mistakes that keep runners from improving.

Zoë and TJ also tackle big listener questions about injury recovery, identity, and how to keep your fire burning when progress stalls. Plus, our Hot or Not segment covers official race photos, trusting weather forecasts, and whether sleep masks really work for runners.

If you’ve ever wondered how to train smarter—not just harder—this episode is packed with practical endurance training tips you can use right away.

This week on the Microcast, Zoë and TJ run through a stack of running myths and training debates—some serious, some a little silly.

First up: Hot or Not. Waist lights? Surprisingly useful. StairMasters? A tool, sure, but not a magic bullet. Then we dive into the trend of weighted vests, sled drags, and other “muscular endurance” hacks. They might look hardcore, but do they really help everyday runners, or just the elites?

From there, we answer a listener’s Reddit-inspired question: does standing at your desk actually build endurance? (Spoiler: “time on feet” isn’t the same thing as running stress.)

Finally, we take on the sacred cow of 3:1 deload cycles. Instead of sticking to the calendar, Zoë and TJ explain why recovery is more personal—and how to spot the real-life signs you’re ready for a down week.

Topics: Hot or Not gear, weighted vests, standing desks, deload weeks, recovery cues.

00:00 – Intro & Welcome

What happens when a hundred-mile race turns into a snowstorm survival test? In this episode, Zoë and TJ break down their very different experiences at the Run Rabbit 100 — from a top-five finish in brutal conditions to making the hard call to DNF.

You’ll learn how ultrarunners can adjust goals mid-race, why safety should always come before ego, and how to recognize when “excellence” means stopping instead of pushing through. We also dive into ultramarathon-induced corneal edema (yes, your vision really can blur mid-race), hydration mistakes that derail performance, and the mindset shifts that help athletes stay resilient when plans fall apart.

🎙️ Topics Covered:

• Mental flexibility when races don’t go as planned

• The decision-making process behind a DNF

• What corneal edema is and how it happens in ultramarathons

• Hydration and fueling mistakes to avoid

• Building toughness and resilience through consistent training

🔥 Race week is here! And with it, taper tantrums, heavy legs, and the mental games that can make or break your performance. In this episode, Coach Zoë and TJ share five evidence-based taper strategies to help you arrive fresh, confident, and ready to race.

You’ll learn why cutting volume (not everything) is essential, how to keep just enough intensity to stay sharp, why sticking to your weekly rhythm matters, and how to stay specific without wrecking your quads. Most importantly, we dive deep into the mind game: how mental fatigue can add up to 45 minutes to your ultra, and practical ways to externalize choices, simplify logistics, and beat decision fatigue at aid stations.

🎙️ In this episode:

• Taper madness, athlete vs. coach brain

• Decision fatigue & the “trash → bottles → food → go” mantra

• Why overpacking hurts more than it helps

• The five-point taper plan you can actually trust

Are ultrarunners at higher risk of colon cancer? Can scrolling before a workout actually make you slower? And is muscle damage( not gut issues) the biggest reason athletes DNF ultras? This episode dives deep into three new studies that every endurance athlete should know about.

Zoë and TJ break down the recent New York Times article on colon cancer risk in marathoners and ultrarunners, explaining why the headlines caused panic, what the data really says, and how to think critically about risk. They then discuss surprising new evidence that social media use before training may blunt your skill development and endurance. Finally, they dig into a groundbreaking study on muscle damage in ultras, why durability may matter more than VO₂max, and practical training strategies to keep your legs from blowing up on race day.
