We use old-fashioned hand-timing, recorded on an electronic time recorder called Time Machine (see that feeds into our proprietary scoring system. Please wear your bib number visibly on the front of your shirt, not obscured in any way, so we can record you at the moment you finish.
  • Please do not remove the name tag at the bottom of your bib number. It is NOT a baggage tag. We pull the tag off the bottom of your number after you finish to establish the order of finish

  • Your time is as shown on the clock. If you plan to run a fast time or to try to qualify for 2018 Boston Marathon or Chicago, Houston, or New York City Marathons who also have qualifying times, please step to the front of the crowd under the START banner after we sing the National Anthem
  • Thus you won't lose 15 to 30 seconds starting back of the crowd. The race is small enough that you can do that
