Rockin' Riverfest 5k, 10k, Half Marathon & Fun Run

Rockin' Riverfest is a multi-distance running event held on July 4, 2026 at Frontier Park in St Charles, Missouri. The courses start near the riverfront and follow the Katy Trail, then continue along shady single-track trails beside the Missouri River before returning to the riverfront and historic district. The event takes place alongside Riverfest activities on the historic St Charles riverfront.

Distances include:

• 5k
• 10k
• 5K fun run/walk/stroll
• Half Marathon (13.1 miles)

Participants pass water and aid stations early on the course, with additional aid stations provided for the longer distances. A Racers Village offers drinks, sports drink, snacks, pickle juice and ice, and music is played there. Event services include professional race timing with instant results and timed splits, custom bib numbers, free downloadable finish-line photos and video, and an awards ceremony on podiums.

All 5k, 10k and Half Marathon participants receive a custom finisher T-shirt (garanteed for registrations completed by June 15) and a finisher medal. Age-group medals are awarded to the top three in multiple age brackets. Packet pick-up is available the day before at Bike Stop Cafe and on race morning in the Racers Village. A portion of proceeds supports the St Charles School District Cross Country program, with local use noted. Visit the organization's website for the most recent information.
