Here we go:
Seafair: 12miles, 32.30, 22.13mph
Issaquah: 15miles, 37min, 24.32mph
I think we can infer that Issaquah is a much faster course since it required less power to go much faster.
I'm using these (vs. chunking in the Bellingham event) since they were flat-ish and the profile on paper at least looked similiar.
At Seafair (unless I was traveling on a descent (rare) and at a very high rate of speed (26mph+) ) I was focused on keeping power near threshold. Higher then that I could feel my legs start to sing.
While at Issaquah, I worked in a window slightly lower then Seafair.
Those times aren't too much to get excited about on flat courses where I had to fight wind. I do have a hilly long-course event coming up where my weight and those power numbers should help nicely. :)
Anybody wanna lend me a Zipp 404 or 808 w/Powertap hub for Lk Stevens? :)
