On April 16 to 19 Atlas Improv Company celebrates 11 years with Madison’s only improv fest – The Endurance. Enter the arena for a TheatreSports throw down, get your true stories twisted into double-jointed realities, and top it all off with 11 straight hours of improv in all its brain-bending, sleep-deprived, leap-taking glory. Featuring a colossal cast of alumni, storytellers and guest troupes, not to mention the Atlas crew you love and laugh at. Best yet, The Endurance is completely free.
