Flat course starting in Marymoor Park heading to Lake Sammamish State Park in Issaquah. Mostly paved and packed gravel, although we had to divert to sidewalks for a couple of miles due to construction. The last couple of miles were irritating, winding back and forth through the huge parking lot....I would say it was like Disneyland--just when you think you are at the front of the line, suddenly you realize you have a whole lot more line to stand I'm. In this case, a whole lot more running to do. But once we made it through that it was around a little corner to the finish line, which was really fun, lots and lots of people there cheering!
