![Tech That Can Take the Guesswork Out of Racing and Fueling](https://cdn.magzter.com/1523556095/1651067344/articles/57F1vXLZ71651237030727/Tech-That-Can-Take-the-Guesswork-Out-of-Racing-and-Fueling.jpg)
THE QUESTION THAT haunts runners after a race-good or bad, personal best or worst-is, Could I have gone faster? Even after Molly Seidel finished third in the 2020 Olympic Marathon, fans wondered if she could have chased down Brigid Kosgei of Kenya for the silver. After all, Kosgei finished just 10 seconds ahead in 2:27:36. The answer might be found on Seidel's Strava, where she posted an unofficial summary of her race in Sapporo. According to the heart-rate data captured by Seidel's Coros Apex watch, it doesn't look like she could have pushed much harder for those last few miles. Her heart rate soared past 180 bpm, holding steady at her near maximum right until she crossed the line. In theory, Seidel was firing on all cylinders.

CAN YOUR GARMIN WATCH REPLACE A COACH?
Artificial Intelligence continues to rapidly creep into seemingly every facet of our daily lives. While no amount of computer learning will ever be able to do the actual running for you, there are aspects, like coaching, where AI could have a meaningful impact. In every debate about Al, the conversation almost always includes this question: Is it better than what humans can accomplish? In the case of running, would Coach AI be better than, say, Ed Eyestone, a two-time Olympian and coach of Conner Mantz and Clayton Young, the top two men at the U.S. Olympic Marathon Trials in February?

HOW TO (NOT) COMPETE WITH YOUR SIGNIFICANT OTHER
Our first race together was a 5K Color Run. I'm not sure why we signed up, because neither of us was a runner, but in May 2016, my boyfriend of three years, Jonathan, and I showed up to run around the parking lot at Citi Field. It was fun, but I didn't think it would amount to anything.

THE ACCIDENTAL JOY OF RUNNING WITHOUT HEADPHONES
I'M FUMING. I rummage through my work tote, turn my workout bag inside out, lift every notebook on my desk, go through the pockets of every piece of clothing in my zone of vision, then my tote again... It's 5 p.m. I'm standing in the middle of the office dressed for a run, but my AirPods are nowhere to be found-and I can't possibly leave without them!
