The Course: Flat, Fast, and Midwest-Fresh
The Kankakee 20k TT course is a classic out-and-back, starting and near Splash Valley WaterPark. Riders head east on River Road, then loop back after 10k—mostly flat with a slight rise over the I-57 overpass. Asphalt and chip-seal surfaces are in good shape, offering smooth rolling despite rural charm.

Expect: Terrain: Flat (0-1% grades), minimal elevation (~50 ft)—ideal for 25-30 mph efforts. Scenery: Golden fields, the Kankakee River’s edge, and occasional barns—pure Midwest vistas. Conditions: May brings 60-75°F temps, 60-70% humidity, and 10-15 mph winds—tailwind out, headwind back (or vice versa). Open to traffic, the course demands caution—ride right, use a rear red blinker (highly recommended), and watch intersections (marshals assist). It’s less technical than Wisconsin’s hilly TTs, making it a speed lover’s dream and a forgiving intro for newbies. Strava data from past years shows top riders averaging 26-28 mph—can you beat it?
