Join us for a morning of friendship, community, and fitness for all ability levels. This is a FREE run that honors the spirit of Rylie Guentensberger who died May 26, 2017 and benefits the non-profit established in her name. All proceeds and donations support Rylie's ARK which is a dedicated to creating a BIG impact through small acts of kindness.
This event includes a timed 5K and festival atmosphere complete with food, drinks, music, games and vendors. We'll have a variety of food trucks for a Make Your Own Mother's Day Brunch as well as beer and a specialty cocktail. Make it a day of fun and celebration with us!
Come out and celebrate with us. All fees are waived for this race, however donations are gladly accepted. A suggested donation of $20, for adult racers, helps fund the ripples and waves of kindness at the core of Rylie's ARK.
The event is free, but we ask you to register so that we can plan accordingly.
We will be offering a race shirt again this year. See photo below for the 2023 edition. Registrations with Rylie's Run Shirts, must be placed by April 28th. We're offering a tank, t-shirt and long sleeve option. Exact shirt color still to be determined.
