About the ROCKIN' RIVERFEST 5K, 10K, HALF MARATHON & Fun Run

The course starts on the Katy Trail and moves into shaded single-track beside the Missouri River, then passes through the historic riverfront district. It is flat throughout, which makes it run fast, and the surroundings shift from trail to town in a way that keeps it interesting. Aid stations are spaced through the route, with sports drinks and ice at each one.

Packet pickup is the evening before at a local bike café, with race-morning pickup available in the Racers Village at the finish area pavilion. After you finish, there is a cold plunge and hose-off station waiting, plus the broader Riverfest is already going on around you, with music, food, and a parade through the historic district.

Common Questions About the ROCKIN' RIVERFEST 5K, 10K, HALF MARATHON & Fun Run

Will I finish last at the ROCKIN' RIVERFEST 5K, 10K, HALF MARATHON & Fun Run?

Almost certainly not. Half the 5K field finished slower than 39:45, and the last recorded finisher came in around 1:10:22, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.

Is the ROCKIN' RIVERFEST 5K, 10K, HALF MARATHON & Fun Run a good first 5K?

A field of 294 is big enough that you will have company at your pace without feeling lost in a crowd. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 5K, that spread matters more than the winner's time.

How competitive is the ROCKIN' RIVERFEST 5K, 10K, HALF MARATHON & Fun Run?

The 5K winner ran 0:04 while the median finisher took 39:45. That spread points to a broad, mostly recreational field rather than a race dominated by club runners.
