The short documentary “Sub Eleven Seconds” follows Sha’Carri Richardson, the American track star and world champion, in the run-up to the U.S. Olympic trials in 2021. Directed by the British filmmaker and photographer Bafic, and produced by the late fashion designer Virgil Abloh, the film focusses less on Richardson’s athletic preparation than on her attempts to make sense of time and all it can hold: victory, glory, reflection, grief, hope.
