Runners get taught one rule from day one: lighter = faster. Creatine is basically the opposite—it usually bumps your scale weight up, and a lot of that is water pulled into your muscles. So my real question wasn’t “will I get stronger?” It was: “will I get slower?” For 100 days I took 3.5 grams of creatine every single day, without changing my life on purpose—same training, same running, same mountain time. In the video I break down what actually happened: the strength gains I saw, the weight gain and what that weight likely was, and a simple Zone 2 test where I ran at the same heart rate before vs after. This isn’t a lab study and I’m not pretending I controlled every variable, but the results surprised me. Instead of getting slower, I ended up feeling more efficient—like I could hold steady effort with less “cost,” especially when fatigue and hills start stacking up. I also talk through the real pros and cons, and who creatine makes sense for (runners who want to be harder to break) versus who should probably skip it.
