DH and I did the Apple Century last year, though last year they did a different route, more of a loop. It went from Wenatchee out to Chelan - had an absolutely GORGEOUS stretch along Lake Chelan, out to Entiat, and back. The support was great and I really enjoyed the ride (with the exception of really wicked headwinds & sidewinds the last 30 miles or so). That was the first century I'd ever done and it was just right, so if this year's route is comparable I bet your friend would have a good ride. We had so much fun I think we're going to do it again this year.
