Alberto Salazar is one of U.S. distance running’s most famous coaches. The world knows of the success that he’s had from coaching Mo Farah, Galen Rupp and Matthew Centrowitz to Olympic medals but many are not as familiar with one of his other success stories.

We’ve partnered with ESPN Films to produce the 30 for 30 documentary, “Bad Boys For Life: The Story of Alberto And Diddy.” The film will follow Sean “P. Diddy” Combs and his effort to run the 2003 ING New York City Marathon.

Alberto Salazar pitched in with a 20-mile run in October.

“Salazar kept wanting to go harder,” Diddy told Sports Illustrated. “He helped me see that you have to be tough. If you ain’t tough, you ain’t made for the marathon.”

In just two months of training and dealing with a bum right knee, P.Diddy was able to complete the 26.2 mile journey from Staten Island to Central Park in four hours, 14 minutes and 54 seconds.

“I definitely wanted to stop,” Combs said in his post-race press conference. “This is definitely a life-changing experience for me because I did not stop.”

Hear from former New York City Mayor Michael Bloomberg, rapper Jay-Z, actor Ben Affleck and singer Jennifer Lopez. All of them donated to the $2 million in charity raised by Diddy for children.

The film will be directed by R.J. McNichols – Director of “Running Away To Flagstaff”
