As a personal challenge for 2016, Mark Zuckerberg will be running 365 miles over the course of the next year.
The Facebook CEO announced his challenge in a Facebook post earlier Monday, where more than 68,000 people liked the post in under and hour.
Here's the full post. Zuckerberg invites anyone who would like to join him in his athletic pursuits this year to this public Facebook group, for motivation and updates.
He has also been responding to comments on his post, like this woman who pointed out that 2016 has one extra day, since it is a leap year.
And this woman, who compared the Facebook CEO to the titular character in "Forrest Gump," where Gump runs across the United States followed by a herd of fans and supporters.
Run, Mark, run!
