					<description><![CDATA[There’s something mildly absurd about modern running tech. Every brand talks about AI now. Smart coaching, predictive training plans, readiness scores, recovery scores, stress scores, you name it. My watch apparently knows my future. It just doesn’t know what happened five minutes ago. Take heart rate. I run with a chest strap or the wrist sensor, doesn’t matter. Every now and then the data goes completely off the rails. Suddenly my pulse jumps to 190 while I’m jogging easy, stays there for three minutes, then drops back like nothing happened. No hill, no sprint, no drama. Just noise. Same with GPS. Clean route along the river, then one glitch and the track cuts straight through buildings like I teleported. The device shrugs and saves it as truth. I can live with imperfect sensors. Sweat, movement, bad satellite reception — physics is messy. What I don’t get is why all that so-called intelligence doesn’t clean up the mess afterwards. Because statistically speaking, this is the easy part. Outliers are not some exotic phenomenon. They’re textbook stuff. &#8230;]]></description>
