Kevin Hart ran 5K with his fans.

The 35-year-old actor and comedian took to his Twitter account on Friday morning (12.06.15) to invite his 19.6 million followers to join him for the jog around Atlanta's Piedmont Park.

He wrote: ''Up & at it...we are about to get this spontaneous 5K run in this morning!!!!''

Kevin added that only those serious about the challenge should come along.

He wrote: ''I'm serious about this. This is about health & challenging yourselves.''

The run - which Kevin organised as part of his partnership with Rally Health - attracted over 100 participants and he told WAGA-TV he was pleased with the turnout.

Meanwhile, the 'Wedding Ringer' star recently confessed he had ''fallen in love'' with fitness and has become a ''fully-fledged workout guy'' despite ''battling'' with the treadmill during every exercise session.

He said: ''I work out every day, and I take off every other Sunday.

''I'm not a big runner, but I try to make sure I put some time in on that (tread)mill. I run anywhere from 2 to 3 miles a day.''
