Mark Zuckerberg, the billionaire founder of Facebook, has a new hobby in mind for 2016—running.
Zuckerberg announced that he’s planning to run 365 miles in 2016, and started a Facebook group encouraging users to join him. More than 70,000 users signed up as of Tuesday.
“This is a lot of running, but it’s not a crazy amount,” Zuckerberg said in a post. “It’s a mile a day, and at a moderate pace it’s less than 10 minutes of running per day.”
Zuckerberg calls the challenge “A Year of Running” and it’s piggybacking his 2015 challenge “A Year of Books” where he read a new book every two weeks.
Zuckerberg interacted with a number of users responding to his post, informing them that he uses the Nike+ running app to track mileage, and even said “we can take a day off” when someone reminded him that it’s a 366-day leap year.
One user chimed in, “I wish I had all the money in the world and time to run 365 miles!”
“You have one of those things,” Zuckerberg responded.
