If you’ve ever found yourself in the second half of a long run debating whether you should cut it short, you’re not alone. Mounting fatigue has a way of inducing that internal discussion among many runners. Making the right decision can feel tricky. On the one hand, you’re already really tired, and you have several miles to go; won’t mindlessly sticking it out put you in a hole and compromise your upcoming training and racing?

With a jaw-dropping 4:18 20th mile, Sabastian Sawe blew up the lead pack and was never challenged en route to winning the 2025 London Marathon in 2:02:27. The Kenyan bypassed the elite bottle station and surged just past the 30K mark, catching the rest of the field off guard. He sustained his push, covering the 5K between 30K and 35K in 13:56, to cement his lead and destroy his competitors’ will. Sawe’s gap at the finish line was exactly one minute.

Uno degli errori più comuni che potresti commettere quando ti prepari per una gara, sia essa una 5K o una maratona, è quello di preferire un riscaldamento leggero, generico, composto da una corsa leggera, un po’ di stretching e al massimo un paio di allunghi.

Conner Mantz ran one of the great Boston Marathons in U.S. history today, placing fourth in 2:05:08, just 4 seconds behind the second and third finishers. Mantz’s time is the second fastest ever by an American on the storied course, behind only Ryan Hall’s 2:04:58 from 2011. Mantz’s training partner Clayton Young also ran well, placing seventh after losing touch with the lead pack in the 20th mile. Young finished in 2:07:04, the third fastest U.S. time in Boston history.

With a big push just before the 20-mile mark, John Korir of Kenya broke apart what had been an eight-man pack and was never challenged after to win the 2025 Boston Marathon. Korir finished in 2:04:45, the fastest winning time since Geoffrey Mutai set the course record of 2:03:02 in 2011. Korir was tripped seconds into the race and fell, but quickly regained his footing. The only immediately visible consequence of his fall was that his bib wasn’t visible on his singlet.

One week before the 2018 New York City Marathon, US Olympian Jared Ward received a package from Saucony, his shoe sponsor. Inside were three early prototypes of what eventually became Saucony’s first super shoe, the Endorphin Pro 1. Ward’s typical marathon race-week workout is four one-mile repeats at marathon pace. He decided to convert the session into an experiment, with the help of Iain Hunter, an exercise science professor at Brigham Young University.

There are two kinds of runners, and you can tell them apart even when they’re not running. There are those who wear their warmest coat on the first cold day of fall. And there are those who wait for the depths of winter to break out the heavy artillery. I’m firmly in the latter camp. If you get all bundled up for Antarctica just because the temperature dips below freezing, you’ve played all of your cards—you have no more moves left for when things get really tough.

When talk about how to run faster turns to exercise science, VO2 max and lactate threshold are usually the subjects. And for good reason: VO2 max (your ability to pump a lot of blood to working muscles) and lactate threshold (your ability to sustain a fast pace without going anaerobic and having to slow) are key to success in every distance from the mile to the marathon. But there’s another important contributor—running economy—to your race times.

Do you want to not run up to your potential in your next race? Simple: Do like most runners, and have your warm-up consist of some light jogging, maybe a little stretching, and perhaps a sprint or two. What’s wrong with a warmup like that? It doesn’t accomplish what you need to race your best. The object of a pre-race warmup is to be able to hit race pace comfortably from the start. A mile of jogging and some toe touches won’t accomplish that.
