About the ride

Get out of the city and enjoy the Puget Sound region's finest rural riding! Flying Wheels Summer Century is a celebration of summer cycling with a Finish Line Festival featuring food, beverages and more.

While there is day of ride registration and no rider limit, those who register by May 21 will have their packet mailed to them for free.


Each route takes you through rural scenery and great rest stops. Those that want hills should ride the 41-, 63- and 96-mile loops. Riders not interested in hill challenges can opt for the 23-mile loop, which has only a couple of gentle climbs. Note that route distance have changed this year due to slight route changes.

The course closes at 4:30 p.m., so remember to give yourself enough time to complete the route you choose.

Route Maps - hard copies will also be available at the start line.

 23-mile loop: Route takes you clockwise around Lake Sammamish and through Bellevue with a few rolling hills and no major climbs. Great for younger riders, beginners and families. Route markers on the ground will be green. Start between 8 - 9 a.m.

41-mile loop: Ride from Redmond to Carnation to Fall City to Issaquah and back to Redmond - three climbs of between one mile and three miles in length.

63-mile loop: Take the 41-mile route; at 17 miles**, turn left and head out to Duvall and back for one more challenging one-mile climb.  Completed at a good pace this is adequate for one-day STP riders.

96-mile loop: Take the 63-mile route; at the 30 mile mark**, turn right and add a ride through Snohomish and Monroe for a total of five good climbs and some second half STP "rollers". Finish this route and you'll know you're ready to enjoy the Group Health STP in one day! Start between 6:30 - 7 a.m. GPS map http://ridewithgps.com/routes/4465129 - 3,627 feet of climbing.

The 41 - 96 mile loops have one master map and tick sheet so on the day of the event if you want to go longer or shorter you have the map. Route markers on the ground will be yellow and there will be road signs at key turns.

(**note:  in deciding whether to do a longer loop, keep in mind that the last hill ~17 miles from the finish is ~3 miles in length at 7-9% -- as the British would say, "You have been warned.")
