Tease your hair, throw on some leg warmers or neon gear and go back in time for the "Totally Awesome '80s 5k."
The race will be held on throwback Thursday June 5 at Grant Park at 6:30 p.m.
DJs will be playing totally rad '80s tunes and participants are encouraged to run, walk, dance or skip the course.
Despite the light-heartedness of the event, organizers say it is a USATF-certified course and chip timed.
Registration is $40 right up until June 4.
It's sure to be a radical good time.
