About Jonah Rosner

After 10+ years working with the most elite athletes in professional sports—including my time with the Houston Texans—I discovered something shocking: The "common wisdom" about marathon training is dead wrong. Now I help runners PR using the same sports science that keeps pros at the top of their game. No BS, just peer-reviewed performance. The result? 70% of our athletes hit personal records within 16 weeks. Here's how. THE PROBLEM I SOLVE: You're logging the miles. Following the plan. Yet you're still stuck at the same pace you ran 2 years ago. Meanwhile, your Instagram feed is full of: → Influencers pushing detox teas → Coaches recycling 1980s training methods → "Experts" who've never read a single study You're drowning in contradictory advice, and it's costing you PRs. WHAT MAKES MARATHON SCIENCE DIFFERENT: 25+ PhDs on our advisory board (not influencers) Every recommendation backed by peer-reviewed research Pro sports methods adapted for everyday athletes Real data: 70% of clients PR (we track everything) I believe evidence beats hype. Always.
