From the Partnership for Downtown St. Louis:
The streets of Downtown will be filled with color this Sunday, September 15th as The Color Run makes its second trip to St. Louis in 2013. This fun-filled 5K will begin at Market & 13th at 9AM, will head West on Market to Compton Ave., turn North to Olive St., turn East to 18th St., turn South to Chestnut St. and turn East to finish at Chestnut & 15th St.
All roads on the route will be closed to traffic, and there will be no parking along the route. In addition to these roads, the highway exits for I-64 Westbound 2100 Market, I-64 Westbound 3000 Market, I-64 Eastbound Chestnut at 20th, and the Pine St. entrance to Eastbound and Westbound I-64 will all be closed from 7AM until 10:30AM.
