I've been wanting to do this ride for a couple of years. There was going to be a large group of us riding, but most have backed out
I've had a great summer, but haven't ridden as much as I normally do because of kayaking, hiking, camping and running. I'm not concerned with the hills since I typically do hills when I ride - it is more the lack of time in the saddle. The longest ride I've done this year is 50 miles (back in early June).
On a bright note....I completed "Ride the Hurricane" a couple of weeks ago (17 miles and close to 5200' elevation gain). A great ride and highly recommend it to folks in the NW area.

Anyway, I'm looking forward to the ride next weekend and it appears that our heat wave has passed. There will be about 5 of us riding together, so it will be fun!
