Why Nutrition Is Crucial
for 10K Runners

(According to One of the Best to Ever Do It)

Shalane Flanagan is among the world’s most accomplished runners. She was the 2008 Olympic 10,000-meter silver medalist and later became the first American woman to win the New York City Marathon in 40 years.

Now, as a coach for the Bowerman Track Club, Flanagan’s training the next generation of 10K champs, including 2020 Olympians Karissa Schweizer and Elise Cranny.

And nutrition? It needs to be on point, says Flanagan. “It’s [about] constantly replenishing. The name of the game is recovery if you want to come back the next day and get in another run, and another hard session later in the week.”

It’s not hard to tell when a runner’s nutrition has fallen off course. “If we see too many days of fatigue in a row, that’s usually a sign fueling might be off,” says Flanagan.

“Especially with female athletes, if they lose their cycle that’s the biggest red flag that they are not meeting the caloric needs. With elite athletes, it’s very easy to have that happen. You just have to catch it and self-correct ASAP because it can lead to excessive fatigue and even bone injuries.”
