  • Zone Compression: What My Mask Test Revealed | Ep21
    Sep 25 2026

    Coach Alicia just found out her zone two had been lying to her.


    After months of easy runs that felt harder than they should, Alicia went through a full metabolic assessment: mask on, treadmill ramping, breath-by-breath data on how her body shifts from burning fat to burning carbs. The result forced her to drop her own lactate threshold and rebuild her zones from scratch, and it's a reminder that a training zone is data, not a trophy.


    In this coffee chat episode (kombucha in hand), Coach JW and Coach Alicia get into what a metabolic test actually tells you, what "zone compression" means, and why more high intensity isn't the shortcut to getting faster. They walk through field test options like the twenty minute test and the bike ramp test, how JW decides an athlete is ready to move up a zone, and why RPE still matters more than any number on a watch.


    Plus: JW's daughter Runa just finished her first 28k trail race at ten years old, mom running alongside her the whole way. The story behind that finish line is worth the listen on its own.


    Fitting the training into the chaos, one zone at a time.

  • The Base Season Training Guide: Strength, Rest, and Avoiding Burnout | Ep20
    Sep 11 2026

    Welcome back to The Endurance Balance!


    Are you treating your off-season as a complete shutdown? In this episode, Coach JW, Coach Alicia, and Coach Anne unpack why taking months off during the winter is the fastest way to flush a full year of hard-earned aerobic fitness down the drain. We discuss the critical importance of reframing these months as your "Base Season" and how shifting your focus to strategic rest, core rebuilding, and heavy lifting sets you up for massive gains next year.


    We dig into the mental resilience required to reduce training volume without entirely abandoning consistency. Learn how to reverse-engineer your upcoming training schedules for future start lines, maintain your aerobic baseline, and tackle your specific limiters head-on without the looming pressure of race-pace demands. As we like to say: respect the base season, work with a coach, and let's fit the training into the chaos.


    In this episode:

    • The Detraining Trap: Why a complete winter shutdown destroys your capillary networks and mitochondrial density, and how to maintain an aerobic baseline.

    • Rebuilding the Chassis: Why winter is the non-negotiable window to put down light weights and lift heavy to build durable tissue and protect your skeleton.

    • Targeting Limiters: How to audit your past race logs to pinpoint specific weaknesses—like hill running power or core fatigue—and establish targeted improvement goals.

    • Reverse Engineering: Planning your future races effectively and mapping out training schedules to avoid overtraining and burnout.


    Takeaways:

    • Reframe the Off-Season: Shift your mindset from "taking time off" to "changing the focus" so you do not start from ground zero in the spring.

    • Lift Heavy: Use the base season's reduced run and bike volume to integrate dedicated core stability and maximal strength sessions.

    • Audit Your Limits: Identify your single biggest limiter from the past season and schedule heavy strength sessions aimed directly at fixing it.

    • Pace Your Mind: Avoid burnout by embracing strategic rest and relying on coaching accountability to build a sustainable, long-term training plan.

  • When to Schedule Your Rehearsal: The B-Race Timeline Explained | Ep19
    Aug 28 2026

    Welcome back to The Endurance Balance!


    You just paid a registration fee, but are you supposed to go all-out every time you cross a start line? In this episode, Coach JW, Coach Alicia, and Coach Anne break down the strategic use of A, B, and C races in your training cycles. We discuss why treating some start lines as heavy training days rather than peak performances protects your physical chassis, optimizes your long-term recovery, and keeps you consistent.


    We dig into the mental toughness required to leave your ego at the start line and how to properly adapt to unexpected course conditions or weather challenges. Learn how to use your B races as high-pressure rehearsals to dial in your fueling, hydration, and gear logistics without the anxiety of a PR attempt. As we like to say: it's never about the race, it's always about the training. Let's fit the training into the chaos.


    In this episode:

    • Defining the ABCs: Breaking down the exact differences and purposes behind your A, B, and C races.

    • Timing and Frequency: Where to strategically place B races in your training cycles to test your fitness without overtraining.

    • The Ego Check: Mental strategies for managing expectations, holding back your pace, and executing your plan on race day.

    • Race Day Rehearsal: Dialing in your fueling, hydration, and transition logistics under real pressure.

    • Adapting and Recovery: Adjusting your training plans for weather challenges and mastering the taper and recovery around sub-goal events.


    Takeaways:

    • Define the Goal: Establish clear expectations for every start line so you know whether you are peaking for a PR, testing logistics, or just enjoying the community.

    • Rehearse the Variables: Your goal in a B race is exactly what you and your coach decided—use it exclusively for gear checks, pace strategy, and hydration testing.

    • Check Your Ego: Focus entirely on your specific training target, even when the cowbells are ringing and other athletes are passing you.

    • Protect the Chassis: Manage your recovery and avoid the makeup-session trap around B and C races so you don't compromise your ultimate A race.
