“I’ve found running is a great way to clear my head, to get more energy and to find time to think about challenges I’m working through at Facebook and our philanthropy. When I’m traveling, running is a great way to explore a new city and kick jet lag before a packed day of meetings,” Zuckerberg wrote.
Zuckerberg said he’s worked on his speed and has run a 5:53 mile, adding that he has stretched his long runs up to 20 miles.
He said although he’s reached his goal, he’s not done running.
“One friend’s New Year’s challenge was to run one more mile than however many miles I run,” he wrote. “I’m pretty competitive, so that’ll keep me going.”
Zuckerberg also revealed that he’s also adding cycling and swimming to the mix, though he recently broke his arm falling off his bike.
Overall, though, Zuckerberg said he is most touched by the Facebook group of people taking on the challenge with him.
“It’s inspiring to see so many people in our community join as well,” he wrote. “Our Year of Running group has more than 100,000 people and every day people share amazing stories of how running helped them get in shape, how the discipline helped get their life on track, or just how they ran a race they never thought they’d be able to do.”
