This weekend, thousands of runners will race in the Louisiana Marathon in Baton Rouge.
There's still time to register - but don't leave out the kids.
300 free registrations are available for this year's Kid's Marathon.
50 students from the "Big Buddy" Program are already registered and training to run.
The free registration comes from Blue Cross and Blue Shield, the sponsor of this year's race.
