Kevin Hart — The "Ride Along" star was in Dallas fulfilling his spontaneous 5K run along with thousands of supporters who joined him. However, one particular participant drew the comedian's attention and inspired him.

The 36-year-old shared Friday on Instagram a picture of himself running alongside an overweight man who seems to be at the brink of finishing the race, according to People.

 "This is why I do it....Simply for moments like this!!!" Ice Cube's co-star captioned the snap. "I saw him a quarter mile out from the finish line and I was so inspired by how hard he was working....I jumped down and ran out to him and finished his 5K with him!!!! Good job man....u are well on ur way to greatness!!!!"

The Philadelphia-native has been organizing spontaneous 5K runs all over the country, and he's already assembled crowds in Atlanta, Boston, Brooklyn, Georgia and New York during the summer. Hart hopes to make his race a "global movement."

In another post, Hart could be seen posing half naked as he is surrounded by a crowd of 5K run participants.

 "Today's run in Dallas was my biggest turn out to date....over 2000 people showed up & showed out," he captioned the photo from Friday's race. "Woooooow....I told you guys that these runs are going to keep getting bigger & better!!! This is a GLOBAL MOVEMENT people!!!! Everyone did a amazing job today. We motivated one another to be great and celebrated everyone's finish with love!!!!"

Meanwhile, Hart and Ice Cube will be reprising their roles as Ben Barber and James Peyton in the sequel to their 2014 box office hit "Ride Along," as per Cinema Blend.

Joining the duo in the Tim Story follow up are Olivia Munn, Sherri Shepherd and Ken Jeong, Variety reported.
