Obliteride Day

What is Obliteride Day?

Obliteride Day is the big event. This is the day of our bike rides and 5K walk/run in Seattle. Show up early, head to the starting line, and complete your 25-, 50-, or 100-mile bike ride or 5K with your fellow participants. All routes will start at the University of Washington E-18 parking lot and finish at Gas Works Park.

100-mile ride: 6:30 a.m.
50-mile ride: 7:30 a.m.
25-mile ride: 9 a.m.
5K walk/run: 8 a.m.

After you complete your Obliteride, enjoy food, drinks, an afternoon of fun, music, and community at Gas Works Park!

Saturday Celebration

You’ve worked hard and crossed the finish line — now, it’s time to celebrate at Gas Works Park! All participants receive a delicious meal and beverages as part of their registration. After you eat, stay for an afternoon of music and camaraderie with a welcoming community dedicated to curing cancer faster. Service animals are welcome; no pets are allowed.

Not an Obliterider but want to attend on Saturday? You can:

Cheer. Cheering at the finish line is open to the public, no ticket necessary.
Pick up a spectator ticket. Free at the door for entry into the Saturday Celebration without food and beverages.
Buy a ticket online. Enjoy food and beverages at the celebration. Tickets will also be available for purchase on-site.

Carefully Created Routes

Our family-friendly 5K walk/run is on a paved path, with mostly foot and bike traffic. Our bike routes are not a closed course, but do use a combination of bike trails, bike lanes, and open roads shared with cars. They have signage, rest stops, support vehicles, and traffic control support. Please note: NO pets, excluding service animals, will be allowed on our bike or 5K walk/run routes, the Friday Night Party, or at the Saturday Celebration.

Rest Stops and Snacks

Bike rest stops offer snacks, drinks, mechanical (bike) support and medical support if needed. Lunch will be provided on-route for 100-mile riders at the mid-point rest stop. Lunch will be available at the finish line for all other routes. The stop along the 5K walk/run includes water, bathrooms, and encouragement.

Support and Gear Vehicles

SAG (support and gear) vehicles track riders on all bike routes. If you need assistance, use our safety app, TraQCentral, or call the emergency number on your wristband.

What We Need From You

To make our day safe and fun, we need help from you.

Obliteride is not a race. Some Obliteriders are new to group riding, running, and walking. Come prepared to be patient and helpful. Finish times will not be provided.
Be prepared. Choose and train for the route that works for you. Watch the weather and bring clothing for rain and sunblock for sun. And if anything comes up during your ride, walk, or run, call the emergency number on your wristband.
A helmet is required for ALL bike riders.

Stay on your marked route, cooperate with law enforcement, follow the rules of the road, and give right-of-way to emergency vehicles.
Educate yourself about cycling safety. Use hand signals to turn and voice to pass, do not wear earphones, and give others sufficient room to ride. Cross railroad tracks at right angles and stay aware of hazardous road conditions.
Call 911 in an emergency.
