A link to the following (and more) was just posted on the Seattle International Randonneurs' Facebook page:
"Registration for the 2018 Cascade 1200 opens at 6am Pacific on Friday February 2nd!
"This year, the event is limited to 100 riders. The ride fee will be $475, with certain discounts available. (See the registration process described below for details.)
In an effort to accommodate as many international riders as possible, registration spots will be allocated as follows: 80 spots will be immediately available to riders from the United States and Canada. These spots are expected to fill within a day. A waiting list will be maintained beyond that.
20 spots will be immediately available for riders from all other countries. If not immediately filled, these places will be held open for international riders through the end of February. Any unfilled international spots will be offered to to wait-listed US/Canada riders on March 1st."
"Registration for the event will be a 2-step process."
http://seattlerando.org/C1200/ will get you to the Cascade 1200 homepage, where this information (and more details) can be found.
As I recall, Pacific Standard Time is GMT -8, so this is about 2pm on Friday. Three days to get the information together which it says you will need to supply.
See you at the finish in Snohomish!
