FREE Running Limiter Quiz + Custom Training Plan: https://nicklasrossner.com/run-limiter/
In this episode, I break down the science of what actually happens inside your body from your very first run to long-term health and longevity.
You’ll learn:
• What happens in your brain after just ONE run (and why you instantly feel better)
• The real science behind “runner’s high”
• How running builds mitochondria — the tiny power plants that make you faster
• Why stronger tendons make you more efficient and injury-resistant
• How your heart physically remodels itself with training
• Why VO₂ max might be the single strongest predictor of lifespan
• Exactly how much you need to run for mental health, performance, and longevity
And most importantly — how to get all the benefits without overdoing it and ruining your progress.
My name is Nicklas. I’m a sports scientist, physiotherapist, and former professional triathlete. I translate complex exercise science into simple, practical strategies you can actually use.
If you’ve ever wondered:
How much running is enough?
Do I need intervals?
Can I run too much?
Is running actually good for long-term health?
This episode gives you the complete science-backed answer.
Run once to feel better today.
Run consistently to get fitter in months.
Run smart to stay healthy for decades.
