Overview
The Oregon Cascades 50M is a fast, scenic, and runnable ultra that connects the Cascade high country to the heart of Sisters. Starting high at Swampy Lakes Sno Park, runners descend through alpine forests, meadows, and technical sections before flowing into long singletrack miles toward the finish at Sisters Middle School.
With 4,000ft of gain and 6,500ft of loss, this is a course designed for speed without losing the big mountain feel. Perfect for first-time ultrarunners and veterans chasing PRs, the 50M delivers jaw-dropping views, generous cutoffs, and an unforgettable finish line celebration in Sisters.

Dogs
Dogs are not permitted on the course or in race shuttles. Pets are allowed at the finish area in Sisters but must remain leashed and under control at all times.
Kids
The race does not offer a separate kids race, but families are encouraged to bring children to cheer at the finish line in Sisters. Children must remain supervised at all times.
Volunteers
Every race has a secret sauce—and it’s not the aid station snacks. It’s the volunteers. Without their energy, smiles, and hard work, none of these events would happen.
Volunteering is a chance to give back to the trail running community, cheer on runners from a different perspective, and maybe even scope out what racing feels like before signing up yourself. Whatever brings you to the volunteer crew, we see you as partners—and we celebrate you like the trail heroes you are.
What You’ll Get as a Volunteer
At Alpine Running races, volunteers receive:
A quality race t-shirt (wear it with pride!)
A post-race meal and beverage—because good food tastes even better after trail magic
Race credit toward a future Alpine Running event
A Few Ground Rules
To keep things fair and sustainable, here’s how volunteer benefits work:
Credits expire within one year of being issued.
Credits don’t apply to volunteers associated with race sponsors.*
Credits and race-day perks are for folks who sign up ahead of time and fill their assigned role.
Credits can only be redeemed online during registration.
Alpine Running reserves the right to adjust credits, restrictions, or benefits if needed.
