How Ultramarathons Affect the Heart, Blood, and Brain

17:26 minutes

Endurance runners braved the grueling Badwater Ultramarathon in the California desert last week, clocking 135 miles and some 17,000 cumulative feet of altitude gain, all in 100-degree temperatures. Ultramarathons seem to be growing in popularity—every week, dozens more are held around the world. But how do extreme endurance sports affect the body? Exercise scientists Tamara Hew-Butler and Greg Whyte talk about how running for dozens of hours can change the heart, blood, and brain. And if you prefer shorter distances, a new study suggests that just five minutes of daily jogging may boost heart health.
