Celebrate over 40 years of Bike MS: Oregon! Enjoy the charming town of McMinnville, located just 40 miles outside of Portland. Our ride will start and end at Evergreen Aviation & Space Museum, with our routes taking you through Oregon’s wine country. The routes will be a mixture of old and new, but either way, the sites will be unforgettable. Get ready to create lasting memories while making a meaningful impact. Together, we'll make this anniversary a milestone to remember!

Nestled in the heart of Oregon’s wine country and 40 miles outside of Portland, our new host town is a warm, inviting, friendly getaway destination. With all new routes, you’ll pedal past vineyards, cross creeks and have relaxing pastoral farmland views. The scenic wine country roads make McMinnville a destination for cyclists of all abilities. Our Rider Village is also taking flight with an exciting new venue and partner, Evergreen Aviation & Space Museum.
