New Riders

Join us as we leave from Redmond on a 25 mile ride around Lake Sammamish at a steady pace, (12 - 14 mph on the flats).

This counter clockwise trip around Lake Sammamish is a mixture of roads and trails. 

We no longer have to ride on the East Lake Sammamish, the construction is done! 

Let's meet at the East Lake Sammamish Trail Park. In the past, some people have had problems navigating to the ride start. If you are in the Whole Foods parking lot, you are close - the East Lake Sammamish Trail Park parking lot is on the other side of the fence from Whole Foods.

Please be ready to ride at 10:00am. 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, and our goal will be to regroup frequently. 

Restrooms are available at the start. We will stop along the way for restrooms at mile 10. We’ll also stop for coffee/snacks at Issaquah Coffee at mile 15.

Bring a spare tube and tools to fix a flat, just in case. Please have full fenders if the roads are wet, or you may be asked to ride at the rear of the group.

Note: If weather conditions meet the weather cancelation 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 at least two hours prior to the start and Ride Leader(s) will not be at the start location.

We hope you can join us!


Cascade is switching to a new website.  Our ride is taking place during the transition so dont worry, just show up for the briefing and to sign the paper waiver at 10 am. Yes, we will use the old school paper registration for this ride only. See you there. 

We'll delay the ride start to 11 am on Tuesday.  We're concerned about cold temperature forecast for the original start time and possibly frosty pavement on the route. It'll still be cold at 11 am but hopefully pavement not too slick.
