From the Organizer
Join us on Saturday, October 10th, 2026 for our annual fundraiser that includes both a 5-Mile Course (timed) and a 2-Mile Course (untimed). All funds raised directly benefit the Jensen Community Center in Amherst, Wisconsin. We welcome runners and walkers of all abilities to join us for a fun run that showcases the heart of Amherst.
Registration entitles participants on race day to a commemorative t-shirt, a commemorative can of River Run beer to take with you home, and the option to purchase a bottle of the limited and highly sought-after Central Waters Black Gold. Pre-registration is required. While same-day registrations are accepted, there is an additional fee and those registrants are NOT guaranteed a t-shirt.
The River Run 5-Mile Course: This takes off and concludes at Central Waters Brewing Co. It is comprised of a winding course through the heart of our downtown as well as a limestone-chipped segment of the Tomorrow River Trail. You will run along the Tomorrow River before heading back toward the brewery. The course is NOT closed to traffic, so runners and walkers must be alert and aware of vehicles.
The River Run 2-Mile Course: This takes off and concludes at Central Waters Brewing Co. It is comprised of a small tour through our downtown, while crossing over the Tomorrow River. The course is NOT closed to traffic, so runners and walkers must be alert and aware of vehicles.
Kids Falcon Fun Run: This is held in conjunction with the annual River Run, to help fund the Jensen Community Center. The Falcon Fun Run is a 1/2 K race that starts and ends at Central Waters Brewing Co in Amherst. The race is limited to kids ages 5 through 10 years old and is a small fee to enter. All Falcon Fun Run participants will receive a SPECIAL PRIZE. Registration OPENS April 1st, so have mom or dad sign you up when they do! There are no registrations the day of the race.
