This scenic seaside 5K in Avon-by-the-Sea, NJ marks its 30th year with a flat, partially shaded route complete with mile markers and water stations to keep you hydrated. The first 1,500 registered runners score a guaranteed race shirt, and everyone gets entered into a raffle with prizes like beach season badges—plus all the proceeds go directly to support the Avon Volunteer First Aid Squad, a 501(c)(3) that's been providing round-the-clock emergency medical services since 1931. Grab your bib and shirt Thursday (5-7 pm) or Friday (6-8 pm) at the First Aid Building, or Saturday morning (7-8:30 am) at the Boardwalk pavilion, just keep in mind that Saturday morning pickup tends to draw bigger crowds.
