Marathon
The GO! St. Louis Marathon, presented by Mercy, is a beautiful point-to-point course that begins in Forest Park and ends on the riverfront in downtown St. Louis. The first half of the course winds through historic neighborhoods and business districts, and passes many famous St. Louis sights - the Delmar Loop, the Central West End, the Grand Center arts district, historic Union Station, and St. Louis’ newest addition - a major league soccer stadium - the St. Louis City Stadium. The second half of the route connects from riverfront streets to Great Rivers Greenway’s Mississippi Greenway: the Riverfront Trail. This fast and flat portion of the course travels along the Mississippi River and in an out and back section before coming back to the downtown riverfront area to complete the race!
Half Marathon
The GO! St. Louis Half Marathon, presented by PNC, is a beautiful point-to-point course that begins in Forest Park and ends on the riverfront in downtown St. Louis. The course winds through historic neighborhoods and business districts, and passes many famous St. Louis sights - the Delmar Loop, the Central West End, the Grand Center arts district, historic Union Station, and St. Louis’ newest addition - a major league soccer stadium - the St. Louis City Stadium. The race finishes on the riverfront in the shadow of the majestic Gateway Arch!
Marathon Relay
Marathon relay teams are composed of four runners, who each run one leg of the 26.2 mile course. Legs are *not* equal in distance, and are chosen based on appropriate exchange points for parking and transportation considerations. All relay runners will receive maps, parking instructions, and relay exchange locations prior to the race.
10K
The 10K run is a great way to be a part of the Marathon Weekend festivities and excitement, with a shorter distance option. 10K participants will begin the race at the finish line location for the full and half marathon (which are a point-to-point course), the beautiful downtown St. Louis Riverfront, and run an out and back course from this location.
