Run Pick of the Month - Tenacious 10
Fast, waterfront 10k and 10 mile races - April 6, 2024.
We really like the scenic route on this one. You'll be running along the waterfront almost the entire time, looping Lake Union, and getting killer views of the Seattle city skyline.
The Tenacious Ten courses are well supported with aid stations every 2 miles. Every participant will end up with a finisher medal and custom race shirt as well.
There is a cap of 900 runners, so don't wait too long to register.
