Consistency vs Intensity: What Most Runners Get Wrong | Floris Gierman

In this first episode of The Endurance Lab Podcast, I’m joined by Floris Gierman — host of The Extramilest Show, running coach, and author of Running Breakthroughs. Floris has spent years interviewing world-class runners, coaches, researchers, and everyday athletes. What keeps coming up is surprisingly simple: Build the engine first and let consistency beat intensity. We talk about how runners (especially in their 40s, 50s, and beyond) can train smarter, stay injury-free, and actually enjoy the process without burning out.

In this conversation, we cover

• Why “no pain, no gain” often leads to injury, burnout, and stalled progress

• The real reason easy running works (and why it’s hard on the ego)

• How to balance structured training with day-to-day flexibility

• Why stress outside training matters as much as training load

• How to use simple check-ins (sleep, HRV, effort) to guide your week

• What Floris would do differently if he started running again today

• The fundamentals Floris believes will make you a better runner in 2026

Key takeaways (especially for runners over 40)

✅ Go slower than you think at first (and you’ll get faster over time)

✅ Train easy most days to build aerobic fitness and recover better

✅ Strength train 2x/week to stay resilient as you age

✅ Sleep is the most underused performance tool

✅ Journal daily to spot patterns and avoid repeating mistakes

✅ Leave your ego at the door (Strava pace ≠ progress)
