The course rolls out from the heart of downtown, passing the Gateway Arch and other iconic landmarks on a USATF-certified, net-downhill route. The flat profile and pavement make it a prime PR opportunity for half-marathoners. Runner reviews highlight easy parking, ample port-a-potties, and post-race perks including free beer, massages, and fresh fruit—plus a cool medal and a tech-blend short-sleeve shirt.
The atmosphere is electric, with live music and local cuisine fueling the finish-line celebration. The event also hosts the National Running Club Championships & Rally, adding a competitive edge. For a well-organized, community-driven race that showcases St. Louis at its best, this half is a standout.
