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.

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.
