If you are heading downtown Saturday morning, expect to see a lot of sweat, blood and tears -- the Coastal Bend Blood Center is hosting their Run for Blood 5K.

The 5K walk/run is a donation effort in which the Blood Center says it can save three lives for every one pint of blood that it receives. It begins at 7 a.m. at Heritage Park.
