About this listen

The Trail Running Briefing is a short, weekly podcast for trail runners and endurance athletes who want to train with purpose. In 5–8 minutes, each episode focuses on one specific aspect of performance: training design, physiology, strength, durability, or race execution. No hype. No filler. Just clear, practical insights you can use immediately. Hosted by Isaac Alcaide, endurance coach, the podcast is designed to be listened to on the move, during easy runs, commutes, or recovery helping you understand your training so you can run better, longer, and with more confidence on the trail.Coach Isaac Alcaide Running & Jogging

  • Episode 5 - Why Consistency Beats Motivation
    Feb 20 2026

    Motivation is a mood, it comes and goes. Consistency is a system, it keeps you training even when life gets messy. This episode explains why relying on “feeling like it” leads to stop-start training, and why the runners who improve most are the ones who reduce friction, pre-decide their sessions, and protect a minimum standard on low-energy days. You’ll learn practical tools like a “minimum viable run” (short, easy, just show up), “if–then” plans for busy or bad-weather days, and simple habits that make starting easier.

    The key takeaway: don’t build your plan for your best days, build it for your worst week.

  • Episode 4 - Why VO₂max Doesn’t Win Ultra Races
    Feb 13 2026

    VO₂max measures your maximum aerobic capacity, but ultra races are not performed anywhere near that intensity. What decides performance is not how big your “engine” is, but how efficiently and sustainably you can use it for many hours.

    Ultra success depends on factors like lactate threshold, aerobic efficiency, fueling tolerance, muscular durability (especially for long descents), and disciplined pacing. Chasing VO₂max through frequent high-intensity sessions often adds fatigue without improving race-day performance.

    Instead, effective ultra training prioritises sub-threshold work, long aerobic sessions, strength for resilience, and practicing nutrition under load. In ultras, the winners aren’t the runners who can go the hardest. They’re the ones who slow down the least.

  • Episode 3 - Why intensity works… until it doesn’t
    Feb 6 2026

    Intensity can drive quick improvements in trail running performance but only for a short time. Hard sessions create a strong training signal, yet they also generate fatigue faster than they build fitness. At first, fitness gains are visible; over time, accumulated fatigue masks those gains, leaving runners feeling heavy, flat, and slower despite training harder.

    The mistake many runners make is responding to this fatigue by adding even more intensity or letting easy runs drift too hard. Instead, sustainable progress comes from using intensity sparingly, building a strong aerobic base, and allowing recovery to keep pace with training stress.

    Key message: intensity should support training, not dominate it.

    Rule of thumb: If intensity is always the solution, it eventually becomes the problem.
