Middle Lake Loop via I-90 and 520 (Mercer Island start)

We have waited for so long and now the 520 Trail is finally open! You may have done a North Lake Loop, a South Lake Loop, and/or a Full Lake Loop. Now, we can do a Middle Lake Loop! :-D.

Please join us at the Mercer Island Park & Ride. We will do the Middle Lake Loop clockwise and maybe run across some other folks doing the same thing going the other direction! We will also check out a new trail through the Arboretum (we will go below our posted pace due to the speed limit on the trail) as part of the Lake Washington Loop before we hop in the new 520 Trail!  Then, we will follow it over to the Eastside to follow the usual Lake Washington Loop route down to the I-90 trail back to our starting point.  Depending on interest, some of us might do an optional loop around Mercer Island once we get back to add another 10-15 miles or so to the ride. 

Please come 15 minutes before the posted start time to hear the safety briefing. Bathroom and water are NOT available at the start, but there are nearby coffee shops (e.g. Tully's on the other side of I-90) and a porta-potty within the first couple miles. Signing an e-waiver on Cascade site (red Register Now button below the ride title) ahead of time is not required, but will make the process of the ride start very smooth for you and the Ride Leaders.

Please come prepared to have fun and take care of yourself in the case of mechanical issues (e.g. tools to change a flat, bus pass or cell phone to call for a ride).  And, if the roads have been wet recently, please be considerate of your fellow riders and have a fender to shield those riding behind you from your road spray :-).

Cancellation Policy: A weather cancellation will be posted two hours prior to the ride start time in the comments section below (NOT in the title) and the Ride Leaders will not be at the ride start. Please check here if the weather is sketchy. In addition to showers and rain, ice and other hazardous condition will cancel the ride.

***Because these trails are still new, we cannot plot the exact route on Ride With GPS. Some stretches we used are currently coded for pedestrians or cars only. PLEASE do not attempt to follow this Ride With GPS route on your own if you aren't familiar with the area!  Also, this is currently a DRAFT form of the route that will finalized the weekend before the ride, and a comment will be added to the comments section below when it is finalized.
