Runners are divided into finishing-time according to when the photograph was made (and assuming the race started at exactly 8:00:00 PM). They are not categorized by your official race time. ...so if you're having trouble locating your photograph, search in a 'nearby' folder. I made every attempt to capture every participant as they finished. However, there were a few times ('clusters' where several people finished at the same time) when I was unable to get a clear view.
