Movie S1
Start of the 2016 Chicago Marathon, as seen from an elevated observation point. Thousands of participants progress towards the starting line in a 200 m long and 20 m wide start corral.
Movie S2
Same as Supplementary Movie S1, after we corrected for perspective distortion and measured the velocity field (color codes for longitudinal velocity). Velocity waves propagate upstream over the whole extent of the corrals.
Movie S3
Two-seconds animated GIF of a part of the static crowd (Chicago 2016). White circles indicate detected participants on a static image. Yellow circles show some participants who were not visible on the static image.
