Lessons Learned from Race Reports

  • If traveling there, no need to rent a car since public transportation is great and it’s fairly easy to find a hotel near the start/finish, or along public transportation lines
  • Sharp turns in the early miles, so be prepared, especially with lots of runners around you.
  • Wave starts with corrals, and in waves, so it helps spread out the field (35,000+ runners)
  • Feels chillier downtown near the start because of tall buildings
  • Weather can be all over the place, so be prepared for hot or cold, or rainy, windy…
  • Not many hills, but several bridges with steel grates, which are usually covered with carpet. Still makes for different footing from regular roads.
  • GPS might not work well in early miles among tall downtown buildings


Type: Loop course all over the city, starting and finishing in Grant Park.

Start/Finish Info: Only runners allowed in start/finish area. Corrals closed 10 minutes before start, so get there with plenty of time.

Hills: Minimal, very flat, fast course. Biggest hill is ~25 feet of gain from mile 22-23
