It’s another sweat-for-a-cause Hayward-area summer weekend.

Saturday morning starts off with the fourth annual 10K on the Bay, a shoreline run that raises money for the Hayward Shoreline Interpretive Center. Last year, a New Yorker (if you consider Rochesterians to be New Yorkers) beat out dozens of Californians for first place. Let’s see if we can do better this time, California.

A little later the same morning, members of the Keep Hayward Clean and Green Task Force will be meeting at City Hall, fanning out and doing their third clean-up of the year, this time in the downtown area.
