Participants in this year's Country Music Marathon are in for a real treat. Country crooner Craig Morgan has agreed to be the race's headlining performer. Sarah Darling will join Morgan at a post-race concert at the Nashville Municipal Auditorium at 7PM on Saturday, April 27.

Every year, the St. Jude Country Music Marathon combines a premier racing event with Nashville's longstanding tradition of offering up good, old-fashioned country music. While runners snake through the city on the half marathon or full marathon route, performers play at stages set up throughout the course.

The race attracts more than 36,000 runners, walkers and kids each year to benefit St. Jude Children's Research Hospital.

When the race is over -- and everyone has properly hydrated and recovered -- the marathon organizers cap off the weekend of festivities with a blowout performance. This year, Morgan and Darling will fill that gap to provide the entertainment.

"As a Nashville area native, I'm proud to represent Country Music and St. Jude and give all the runners a chance to let loose after the big race," Morgan says in a statement. "Save up some energy for the end of the night because we're gonna make sure you leave Music City with a lot of great memories!"

Complimentary tickets to the show are provided to all race participants, but runners may purchase additional tickets for $35. For more information about the Country Music Marathon or Morgan's performance, click here.
