About this race
Help raise funds for kids' free dental care on the Tooth Taxi
by registering for The Dental Foundation of Oregon's inaugural
Floss & Run!
Sunday, October 18, 2026, at Rock Creek Country Club
5100 NW Neakahnie Avenue, Portland, Oregon, 97229
You'll be on a professionally-rolled, gently challenging golf path in a peaceful and private setting under giant Douglas Firs. (Course maps can be viewed at dentalfoundationoforegon.org on the "Events" page under "About").
The golf path is paved, but Mother Nature has dropped pinecones and needles and there are a few spots in the cement with tree roots protruding. Please watch your step and move onto the grass, if needed, especially if you are passing.
Timed races include:
*A 1K race for children 11 and under starting at 8:30 a.m.
*A 5K run open to runners of all abilities starting at 9:20 a.m.
*A 5K walk that begins at 9:30 a.m.
All registered participants will receive a re-useable swag bag with a cool Tooth Taxi headband, dental- and health-related items, a raffle ticket for a chance to win prizes from our amazing local sponsors, and free entry into a putting contest!
Additional raffle tickets and putting contest entry may be purchased on site for $10.
Each finisher receives a medal and there are medals for the top three finishers in each age category. Top two teams also win a team prize.
Our host, the Rock Creek Country Club, has a bar and grill with drinks and food for purchase. Parking is free. Please leave furry friends at home. 😊
We encourage attendees to wear their finest dental-related attire! There will be many opportunities for photos with Mo the Molar, Flossie the Floss, Tilly the Tooth Fairy, etc.
Not in the Portland area or can't make it on October 18? There are virtual race opportunities!
We are grateful to our major sponsors: BnK Construction and Permanente Dentistry (crown sponsors); and Columbia Healthcare Banking, Delta Dental, and Willamette Dental (molar sponsors). A full list of sponsors can be found here . We have some incredible raffle prizes and race incentives donated by our sponsors!
