As runners in the 41st annual Chicago Marathon bustle their way toward the finish line, the mellifluous melodies of the King of Rock will break the silence between breaths.

A few miles north of the King of Rock at mile 8.8, Chicago’s LGBTQA running-and-walking organization, the Frontrunners/Frontwalkers, celebrate athleticism and queerness. For the past 28 marathons, the Frontrunners/Frontwalkers have put on a themed song-and-dance performance at their water station. At the 2017 marathon, four “Dancing Queen” Frontrunners/Frontwalkers dressed as ABBA, moved and grooved to the hits of 1970’s pop stars with pride flags in hand. This year the Frontrunners will celebrate a “MARVELous Marathon” at the four corners of Melrose Street with two stages, a DJ, and six to ten performers in superhero suits.
