SINCE STARTING MY first marathon training last summer, I’ve been making sure I eat enough, especially before runs. There are plenty of fantastic sports nutrition options. Many of these products—I’m sure you’ve gotten Instagram ads—promise sustained energy from natural sources. I love munching on the latest snacks marketed to runners, but they’re not cheap! And since I run about 70 to 80 miles a week, I go through them quickly. It adds up. So I’ve decided to save some cash and stock up on products close enough to the sport-specific options. Think: things you could buy in bulk at Costco or your local grocery chain. To see if my budget-friendly choices were also nutritionally sound, I called up Amy Stephens, RDN, CSSD, sports dietitian for the New York University track…

ALSU KURMASHEVA RIPPED the strings off her face mask and carefully threaded the soft ends through the eyelets of her running shoes. The Puma Velocity Nitro 2s were in good condition—her husband Pavel had given them to her only five months ago—except that her captors at the SIZO-2 detention facility in Kazan, Russia, had confiscated the laces. “How am I supposed to walk with my shoes flopping?” she asked a guard. No answer. There was rarely an answer to any question. She realized the jailers didn’t want prisoners to walk freely, but to shuffle around the exercise courtyard in defeat. Alsu wouldn’t surrender so easily. What if she yanked the strings off her mask and fashioned makeshift laces out of them? The experiment worked. Alsu could walk in an almost…

AT THE END of 2022, I sat down with myself to reflect on the changes I wanted to implement and set the priority to embark on a fitness journey in the new year. After an eye-opening moment a few days prior, I calculated that my BMI put me in the obese category (although I now know the stat alone isn’t an accurate indicator of health). That, combined with seeing a pattern of genetic health disorders throughout my family and fearing this reality could be my very own, I knew it was time to get healthy. I hit the gym three times the week before the holidays, with the intention to get the wheels turning on this new habit right away so that I would be spared the curse of failed…

ON CLOUDBOOM STRIKE LS $330 | 6.2 oz (M), 5.2 oz (W) | 4 mm YOU’VE PROBABLY SEEN On’s new shoe on social media. The company set the running world abuzz when it displayed a robot that spun and twirled a shoe around while it sprayed a plastic material that would become the laceless upper. (Think of it as a highly precise hot-glue gun.) The process takes just three minutes, and when it’s over, you’re handed a shoe that’s still warm. It’s a neat concept that makes for an exceptionally lightweight shoe. There’s a bit of a learning curve to getting your foot inside—you have to use your fingers to work the sides up around your foot, much differently than a normal shoe you slide into. Once on, we found…
