Ride Description: 


***PLEASE NOTE*** Due to limited availability of Ride Leaders, this season's CATS will be offered only at Brisk pace unless Vigorous RLs are available. When we do, they will be posted separately. Vigorous riders, please join us anyway and you can leave us in the dust :-).

Come ride with us on Cascade Advanced Training Series at Magnuson (CATS-m)! We are here to help you get ready for Flying Wheels, Seattle to Portland in one day (1-day STP), Ride from Seattle to Vancouver and Party (RSVP) and other long distance ride events you put your mind to while enjoying scenery and company. 

CATS-m is held every Saturday from April to August from Magnuson Park. Mileage and total accumulative elevation gain will increase every week. The mileage ranges from 40 miles up to 125 miles before STP. Although CATS-m is a series, everyone is welcome to join at anytime of the season. 

Each route has a stop every 20-25 miles for restrooms and water refilling. Longer routes will also include one longer food stop at cafe or grocery store. However, each rider should carry his/her own water, food and snacks at the start of the ride. Every rider is also expected to have tubes/tools and to be able to fix a flat and other minor mechanicals.

We will try to split the group by hill climbing skills when enough Ride Leaders are available. If you go too fast/too slow for the pace, you will be asked to ride separately from the group. Every rider is expected to sustain and complete the route at the advertised pace without pacelining/drafting. If you become slower towards the end of the ride, be prepared to complete the ride by yourself and/or cut the route short (carrying ORCA card helps). Please bring a cue sheet and/or upload the route information onto your GPS device/smart phone.

***The final version of Ride with GPS link will be provided by Wednesday prior to the ride date in the comment section below.***

Even though it's not a requirement, we appreciate you register/sign e-waiver (register button right below the ride title) so that we can better plan to have appropriate number of Ride Leaders available. It will make the pre-ride process very easy, too.

In addition to steady rain, any other hazardous conditions will cancel a ride. If a ride is cancelled due to weather and hazardous conditions, it will be posted here in the comment section 2 hours prior to the start time and ride leaders will not be waiting at the start.

Note: Restrooms are at the start. 8am is a roll out time. Please come at least 15 min before the start time to sign a waiver and listen to the safety and route briefing

I plan to intercept in Lake Forest Park, mile 5.7 and later peel off either downtown Edmonds or Richmond Beach
