Rylie's Run
Sunday, May 10th 10:30am*
Douglas County Event Center, Castle Rock

Join us for a morning of friendship, community, and fitness for all ability levels.
This is a FREE run that honors 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. 

Event includes a timed 5K and festival atmosphere complete with food trucks, music, games and vendors.

*Given the current climate surrounding COVID-19, we've elected to postpone the event.  Once things settle down, we'll reschedule and reopen registration.  Be sure to follow us on social media (Facebook and Instagram) for updates.


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 shirt again this year.  If you are interested in a shirt, please use this form to select your size preference, etc.  Shirts will be $20 for short sleeve and $25 for long sleeve.  We will accept 'orders' through May 2nd.  Payment will be made at pick up.
