April in Skagit is all about tulips, and at the 37th annual Skagit Valley Tulip Run, you can join in on the festivities while working on your fitness! The 2-mile run starts at 9 a.m., and the 10K starts at 10 a.m. The runs will be chip-timed with an awards ceremony after, but no aid stations will be along the route, so be sure to bring your own hydration and snacks!
