About the Tenacious 10
The course loops Lake Union, starting and finishing at Gas Works Park. It passes Lake Union Park, crosses the Fremont Bridge, and at one point the Space Needle is in view. The route is flat throughout, so most of the mental work is just keeping pace rather than watching for hills.
Chip timing includes mile splits and live tracking, so people following along remotely can see where you are on the course. Professional race photos are free, which means you are not deciding at the finish whether a photo is worth buying.
