Have done those routes multiple times, Sue; you'll enjoy them! Chilly Hilly: prep for crowds and not-so-nice weather (first time, I rode through sun, quickly turning to hail and sleet to finish - careful on Bainbridge's twisting hills! Daffodil has iffy weather too, but routes are pretty and it's a great atmosphere...not as crowded as Chilly Hilly and no worry about thousands of bikes lying down on the ferry and someone stepping into your spokes - ouch! You live in that area (Orting), so chances are you've driven much of that route already...Have you done the STP before? I remember going to the training seminar that Cascade puts on multiple times beforehand...lots of good prep and training info, especially that you should train for mileage, not hills. Watch the CBC site for schedule and info. Crowds at the UW start there too and it's usually the most dangerous when there are so many people - many beginning road/group ride riders too - getting underway. They stagger the starts and all 1-day riders are supposed to have about a half an hour lead, but no one monitors it and so anyone who wants can start at the 1-day rider time. It's a terrific experience though, well planned and well-supported. Haven't done the actual Courage Classic ride, but have been on rides each leg of the route...you'll love Blewett Pass - on Day 2, I think between Cle Elum and Leavenworth...have fun!
Tailwinds to you.
