St. Louis Track Club Frostbite Series Half Marathon & 4-Mile

Saturday, January 20, 2024 • St. Louis, MO • Course Map

Part of a series of five road races hosted during the winter season each year — including a 12K & 3K and a 10-mile and 2-mile race in December, a 20K & 5K race in January and a 15K & 3-mile race in February — the St. Louis Track Club Frostbite Series sees a few hundred runners cross the finish line every year at this race’s annual wintertime running.

The race takes runners on a double-loop course inside and through Forest Park, a nearly 1,300-acre park that lies just west of the city’s downtown district and a few miles from the Mississippi River flowing by.

Like the other four races in the Frostbite series, the half marathon starts and finishes at the park’s visitor center on Grand Avenue, which lies just inside the northern end of the park off Lindell Boulevard.

The course for the race will take runners through some of the park’s signature attractions, like the St. Louis Zoo, History Museum and Art Center, as well as its Muny Opera, and through some of the streets just outside the park, which opened in the late 1870s and is some 500 acres larger than New York City’s Central Park.

The race also hosts a 4-mile run, which starts with the half marathon at 8:30 AM — or 8:00 AM for walkers who expect to take longer than the runners.

    Ran this one this year (2018) and it was okay. The weather was nice as was the price. It’s a two loop course, which wasn’t as bad as I thought it was going to be. It was nice to know what to expect the second time around. What i didn’t like was the fact that the course was open to traffic. At times, was a bit inconvenient. Add this to the fact that the runners weren’t following the cones and were on all sides of the road. Finally, one of the mile markers were non existent. Hard to pace yourself right for those focusing on their pace. Post race items was no frills. Keep all that in mind if running this one.
