100-mile Classic
The 100-mile Classic is a beautiful century tour throughout the greater Seattle area which stretches into the foothills of the Cascades just outside of Issaquah. Throughout the century experience, riders will begin their journey hugging the Lake Washington shoreline through mid-century neighborhoods and waterfront parks with Mt. Rainer in the background. As riders head just south of the lake, they will tour through the airfields of Renton and climb their way from mile 20 to mile 40 through the equestrian farms of Covington and Maple Valley. Once approaching Issaquah, the 100-mile Classic riders will enjoy looping around Lake Sammamish where views of the Olympic mountains paint the perfect picture for an afternoon ride on a bike. After looping around Mercer Island, cyclists begin their descent back into the city where they will join the 50-mile riders and finish their route towards Gas Works Park and the Obliteride Finish Line. Please note that while this ride provides an excellent tour, it does require a level of comfort with sustained elevation gains and descents for each rider. Check out our route stop map for specific locations, and check out our Ride with GPS map.
100-mile Challenge
Challenges come in many forms and this year we have the perfect option for those looking for a little bit extra on their route. The 100-mile Challenge follows the same route as the 100-mile Classic with a little extra loop mid-route just outside of Issaquah where riders can tackle the challenge of climbing up and over Tiger Mountain. This century plus option brings the 100-mile Challenge to a whopping 5,500+ feet of climbing. During the challenge riders will be given an opportunity to take on the King and Queen of the Mountain (KOM/QOM) as they pedal their way to the top. Once they descend from their victorious climb, riders will meet up with the 100-mile Classic where they can re-join their friends and family and continue to ride through the Obliteride Finish Line at Gas Works Park.
