90% of runners make this mistake (and it has nothing to do with pace).

You're not failing because you're not trying hard enough. You're failing because you're running too hard, too often — and there's actual science behind why that's destroying your progress. In this video, I break down the one mistake 90% of runners make that has nothing to do with pace, shoes, or motivation. We go deep into the three pillars of running science — VO2 max, lactate threshold, and running economy — and why ignoring even one of them keeps you stuck. You'll also learn why that burning feeling in your chest isn't a lack of oxygen (it's CO2 buildup), how rhythmic breathing and forced exhalations can transform your next run immediately, and why the 80/20 training rule is the most ignored piece of endurance physiology for everyday runners. Whether you're training for a marathon, chasing a half PR, or just trying to run farther without falling apart, this is the episode that reframes everything. If you're serious about running faster without constantly feeling destroyed, this is the starting point. Hit subscribe and don't miss next week — we're going straight into lactate threshold training and exactly why you hit the wall at mile ten. #RunningTips #VO2Max #MarathonTraining #Zone2Training #EnduranceScience If you’re enjoying the content and want to support Running for Health, you can make a small donation here: Every contribution helps keep this channel alive and allows me to keep creating better videos for you.
