About the ride
Get out of the city and enjoy the Puget Sound region's finest rural riding! Flying Wheels Summer Century presented by Raleigh 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 45-, 65- and 100-mile loops. Riders not interested in hill challenges can opt for the 25-mile loop, which has only a couple of gentle climbs.
The course closes at 4:30 p.m., so remember to give yourself enough time to complete the route you choose.
Route Maps will be posted here in April - hard copies will also be available at the start line.
25-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. Start between 8 - 9 a.m.
45-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. This is a perfect training route for two-day Group Health STP riders. Start between 7:30 - 8 a.m.
65-mile loop: Take the 45-mile route; at 18.0 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. Start between 7 - 7:30 a.m.
100-mile loop: Take the 65-mile route; at the 30.9 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.
(**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.")
The Flying Wheels route has an estimated 3,840 cumulative feet of elevation gain. This is an estimate; your readings may be different.

Bike to the start line
Save the gas and add some miles. Bike to the start! Marymoor Park is easily accessible by bike via the Marymoor Connector Trail, which connects both the East Lake Sammamish Trail and the Sammamish River Trail to the start line area.
From I-5 north take the SR 520 exit just north of downtown Seattle heading east toward Redmond; from I-5 south take either I-405 or I-90 to I-405 and go north to SR 520 east toward Redmond. Stay on 520 for approximately 7 miles and take the exit to King County's Marymoor Park (W. Lake Sammamish Parkway).
At the light at the bottom of the exit take a right, then at the next light take a left into the park. Follow the road through the park and then follow the Flying Wheels parking signs near the east end of the park. Registration is in the parking lot in front of the baseball fields at the east end of the park - please, no rider parking in this lot. Follow the signs to the Flying Wheels parking area where Flying Wheels riders park for free.
