Bob Barnhill made an excellent report on his validation and his measurement was in good agreement with that of Tom McBrayer. As certified, the course was 0.062% long without the 0.1% SCPF. I have suggested that a U-turn be extended from 12 ft to 25 ft from a reference pole to create a prevalidated course with the full SCPF.
Bob found that the course was not actually run as certified, but a 0.49-km section was run on parallel roads. However, the course as run was still 0.035% long, so Ryan Hall’s record is likely to be ratified.
