You Didn't Get Slower. You've Been Training Wrong.

You didn't get slower with age. You've been training the wrong way — and that's fixable. If you're chasing sub-3 or sub-3:30 and your paces have stalled, you've probably decided it's your age. It almost never is. This breaks down what actually changes after 40, what doesn't, and why most plateaus are a training problem, not a ceiling. Most men over 40 blame their age for missing sub-3. In my experience coaching runners, it's almost never the age. One thing does fade — the very top of your engine, your VO2max. But the things a sub-3 marathon actually runs on — your lactate threshold, your efficiency, your ability to hold pace deep into a race — barely age at all. And even that engine decline is mostly detraining, not biology. There's a reason most runners plateau for years: they're not at the limit of their body, they're at the limit of their method. Fix the training, and the breakthrough that follows is real. This video covers what changes after 40, the numbers sub-3 actually demands, and the shift that decides whether you get there.
