About that men's 800m race at the 1984 Olympic Trials:
I highly recommend reading this excellent piece by Track & Field News writer Jeff Hollobaugh. Here's an excerpt:
The results, when the athletes saw them, were difficult to comprehend. Jones had won in an American Record 1:43.74. Gray, in second, produced the same clocking and thus tied Jones‘ new record. They had both skipped completely past the 1:44s in their leap from national class to world class. “When I looked up at the clock, I couldn’t believe the time,” recalls Gray. Third, in the closest of verdicts, went to unheralded Marshall. He and Robinson both clocked 1:43.92, just 1/100th of a second slower than Rick Wohlhuter’s American Record at the start of the race. Marshall had skipped over not only the 1:44s, but the 1:45s. “I thought the scoreboard was broken,” he says. Veteran Robinson could only have been stunned at the thought that the fastest race of his storied career didn’t put him on the Olympic team.
To that point in history, only 21 times had the 1:44 barrier been breached, and never by more than two men in one race. That four would do so at the U.S. Olympic Trials made the world sit up and take notice.
