Video of a series of runners filmed at 300 frames/sec near the ~17.5 mile mark of the 2010 Boston Marathon (on Washington St. near the intersection with Commonwealth Ave.). All were on a sub-3:00 marathon pace at this point in the race. Note the barefoot runner near the middle of the clip. Courtesy of http://www.runblogger.com.
