The longest-running half marathon in the St. Louis region is back, and this year runners enjoy brand new Half Marathon and 5K courses.

 

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.

 

Prizes and awards:

• Half Marathon: Prize money awarded to the 1st, 2nd, and 3rd place male and female overall finishers.

• 1st place: $500

• 2nd place: $250

• 3rd place: $100

• Age Group Awards: Recognizing the top 3 finishers in each age group, male and female.

• 5K: Overall awards for the top 3 male and female finishers only.
