Based on DCist photography contributor Brian Knight‘s photographs, yesterday’s Marine Corps Marathon was a passionate whirlwind of emotions: elation, sadness, struggle, and whimsy, all in a blur of movement and color. It’s appropriate then, that such an exhausting event required an earlier-than-roosters wake-up call for our intrepid photographer — of course, DCist managing and arts editor Heather Goss (who somehow escaped the reach of Brian’s lens) just had to do him one better and actually run the 10K yesterday.
