Join us for a ride from Redmond's East Lake Sammamish Trailhead (behind Whole Foods) on a 34 mile route at Steady Pace (12-14 mph)!

This quiet, somewhat hilly route explores the trails and backroads of Sammamish. From the East Lake Sammamish Trail, we will warm up with a climb up the Sammamish Plateau via Louis Thompson Rd and wind through quiet neighborhoods to our first rest stop at Pine Lake. Continuing on, we will enjoy dramatic views of Mt Si and the Cascade Range rising above the Snoqualmie Valley. Our next rest stop takes us to Beaver Lake Park and onward to our lunch stop at Starbucks. After lunch, we will climb our final hill before enjoying a long winding downhill back down to Lake Sammamish.

Let's meet at the East Lake Sammamish Trailhead and please be ready to ride at 10 am. We will start with a required safety briefing, and roll out when that's done.  If you miss the briefing you will not be able to ride with the group.

We will climb and descend hills at our own pace, regrouping at the top. Our goal will be to regroup frequently along the route.

Portable restrooms, but no water are available at the start. We will stop along the way for restrooms/water at miles 10, 18 and 27. We’ll also stop for coffee/snacks/lunch at Starbucks at mile 27.

Bring a spare tube and tools to fix a flat, just in case. Please be prepared for wet conditions with fenders.

Note: If weather conditions meet the weather cancellation criterion listed above or if there are unforeseen hazardous riding conditions or other unexpected events, the Ride Leader will post a ride-canceled note in the Comments section below by 8 am and Ride Leader(s) will not be at the start location.

We hope you can join us!


It is raining steadily here in Sammamish, BUT the hourly forecast calls for it to start tapering off around 9-11. Radar is also showing some clearing heading our way. I will be at the start and will make a call at 10. Worst case scenario, we can wait it out at Peet's for a bit. If we decide to make a go of it, it will be a very wet ride, so fenders are highly recommended.
