EDIT: By the way, Marymoor is one of the smoother tracks in the US in my experience. Not as good as Carson, on par with Trexlertown and Colorado Springs, certainly better than Hellyer and Washington Park Bowl, and probably better than most others.
originally, Marymoor had a grooved surface. The idea of the engineers was that would allow it to be used when wet. They weren’t track riders. The riding community went and got grinders and smoothed out the surface. The county also has done a good job of maintaining the track as has the velodrome association.
