The Steens Rim Run is a running and trail running event held on Saturday, August 1, 2026.
Get ready for a spooky-good time at the Monsters & Mimosas 5K, where Halloween fun meets festive celebration! This spirited run invites ghosts, goblins, and costumed creatures of all kinds to hit the course for a frightfully fantastic fall morning.
Join us at Diamond Lake Resort where all race participants will receive a custom finisher medal, a race-themed shirt, and a refreshing mimosa waiting for them at the finish line—because even monsters deserve a little sparkle after a solid run! We'll have juice and water for those under 21.
We’ll also be recognizing top finishers with awards in the usual five-year age groups starting at 10 & under, giving everyone a chance to show off their speed along with their costumes.
Join us for miles, mimosas, and a whole lot of Halloween magic!
