@skialex Actually, Wade Cox ran 39 (1@41) on June 19, 1991 in Miami, FL, breaking Bob LaPoint’s record of 5 at 39 that had held since 1984. Jeff tied the record on July 1 of the same year in Madison, Ga. Jeff, of course, was the first to run 41, both at 36 and 34.
These are, of course, record tournament scores. If you know of a Class C score of 6@39 or better prior to 6/19/91, I stand corrected. In my book, that would still be a first and the score would count (no ranking list back then, though), but it would not be a record and would not go in the books as such.
