Kevin Hart invited Twitter followers to impromptu 5K

Before arriving at his comedy tour stop in Boston, Kevin Hart decided to do something with his fans. How about a spontaneous 5K run?

The fit comedian followed through, and Periscoped part of the run. (Warning: Hart curses in the video.)

He posted that "nearly 300 fans" showed up to work out, and to take photos of Hart, natch.

"This is gonna be my new (thing) every week," Hart said in the Periscope stream.

We'll run with you in Los Angeles, Kev!
