Choose the distance that challenges you and join an outstanding community. And remember — it’s a ride, not a race! Obliteride does not track or post official finish times.
25-Mile Ride
On this route, you’ll enjoy scenic water views as you travel out and back along Lake Washington using Seattle’s iconic 520 floating bridge. The route features gradual climbing and light urban riding and is primarily on protected bike paths or bike lanes, making it great for entry-level riders and all those looking for a beautiful and shorter ride.

50-Mile Ride

Due to external factors (such as weather, road conditions or construction) all timing and routes are subject to change. There will be a number of safety and support elements for Obliteride on August 9. Any pre-event training on the Obliteride routes must be done at your own risk.

Obliteride puts the fun in fundraising. It’s an incredible ride! The community, routes, food and drink, and great cause make it a staple on my calendar every year.
