Those “no parking” signs along Duwamish Head reminded us to remind you: Alki Avenue SW will be closed for a while Sunday morning for the Cosmo 7K, rescheduled because of last month’s wildfire smoke. It’s a 7K run and 5K walk/run, starting at 9:30 am from Alki Bathhouse, followed by a 10:30 am kids’ run (10 and under); last-minute registration will open at 8 am. Part of the proceeds benefit Northwest Hope and Healing.
