About Race 13.1 St. Louis

Slide into St Louis and revel in the unique vibe of the largest city in the Great Plains. Beer, bowling and baseball are some of the top attractions, but history and culture, much of it linked to the Mississippi River, are a vital part of the fabric. And, of course, there’s the iconic Gateway Arch that you have seen in a million pictures; it’s even more impressive in reality. Many music legends, including Scott Joplin, Chuck Berry, Tina Turner and Miles Davis got their start here and jammin’ live-music venues keep the flame burning. With that being said, the Race 13.1 St. Louis Half Marathon is the place to be.

Part of a growing series of Race 13.1’s events across the southeastern U.S., the Race 13.1 St. Louis Half Marathon & 5K takes the Race 13.1 series to the midwest.

The race will again start and finish at Missouri Research Park, a 200-acre research and development park in St. Charles County, and will feature a course filled with scenic greenways and beautiful views of the Missouri River and conservation areas. The looped course will follow local trails, including the Busch Greenway, Katy Trail and Hamburg Trail.

With temperatures in the mid-60s to low 70s, this race will be a beautiful late spring race for runners looking for a great destination race! Be sure to make time to take in all St. Louis has to offer: visit the iconic Gateway Arch or Six Flags St. Louis, take a tour of the historic Anheuser-Busch Brewery (if you're 21 years or older!) and take in some live blues music in the entertainment district in the heart of downtown Ballpark Village St. Louis.


The half marathon begins and ends in Missouri Research Park in St. Charles, MO, taking runners through 13 miles of scenic greenery and conservation areas. The first several miles of the course take runners along the Missouri River west of St. Louis onto the Busch Greenway.

From there runners will run through the Weldon Spring Conservation area, running through the Katy Trail, Hamburg Trail, and Busch Greenway again throughout the half marathon. Runners can expect moderate changes in elevation throughout the course, with long downhill and uphill stretches throughout the course.
