Hundreds, if not thousands, of folks will be lacing up their running shoes this spring all over Westchester to help fight a deadly disease.

The community-led events will be held in: Eastchester, Mamaroneck, Chappaqua, Harrison, Katonah-Lewisboro, the Tarrytowns, Yorktown, Yonkers, Somers, Ossining and the Hendrick Hudson School District.
