The longest-running half marathon in the St. Louis region is back! 

​

Both races start and finish at the Muny Festival Grounds, and maps can be found below.

 

We use an “Open Start” format, meaning there will be a formal half marathon gun-start at 7:30 AM, but you may start your half marathon race any time between 7:30 and 7:40 AM. For the 5K, there will be a formal gun-start at 8:00 AM, but you may start your 5k race any time between 8:00 and 8:10 AM.
