On Obliteride morning, be part of the excitement as you complete your Obliteride bike ride or 5K with an amazing community united to cure cancer faster. Then, let’s celebrate! We’ll have food, music, and drinks waiting after you cross the finish line until 6 p.m. at Gas Works Park in Seattle.

What is Obliteride Day?

Carefully Created Routes

Our family-friendly 5K has been updated for 2023 with a new route! The walk/run is on a paved area, with mostly foot and bike traffic. Our updated bike routes share the road with cars. They have signage, rest stops, support vehicles, and traffic control support. Please note: NO pets will be allowed on our bike or 5K routes, at the Friday Night Party, or at the Saturday Celebration. This policy will be strictly enforced.

Rest Stops and Snacks

Bike stops offer snacks, drinks, mechanical (bike) support and medical support if needed. Lunch will be provided for 100-mile riders at the mid-point rest stop. The 5K stop includes water, bathrooms, and encouragement. Our volunteers and staff make stops a fun way to recharge!

Support and Gear Vehicles

SAG (support and gear) vehicles track riders on all bike routes. If you need assistance, hail a SAG vehicle 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.

  • Be prepared: Watch the weather and bring appropriate clothing for rain — and sunblock for sun. Choose and train for the route that works for you. And if anything comes up during your ride or 5K, call support.
  • Stay on your marked route, cooperate with law enforcement, and give right-of-way to emergency vehicles.
  • A helmet is required for ALL bike riders.
  • Obliteride is not a race. Some Obliteriders are new to group riding. Come prepared to be patient and helpful.
  • 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.
  • Wear your Obliteride wristband all weekend. It comes in your packet and has the emergency contact number on it.
  • Call 911 in an emergency.

Parking and Accommodations

Finish Line Recovery

Join us at the finish line for stretching sessions led by The Yoga Shala to help you recover at the end of Obliteride Day. Stop by the recovery tent at the top of every hour to join a short, beginner-level yoga session with a focus on stretching and recovery. Obliteride participants also receive one complimentary class at The Yoga Shala before Obliteride Weekend. Once you register, check out your Participant Center for more information on how to sign up for your class.
