I've always been amazed at the speed, strength, and jumping ability shown by decathletes. Attention to this first happened back in my youth, seeing teenagers Bob Mathias and Milt Campbell in the '48,'52, and '56 Olympics. That said, the Kevin Mayer of France would have my vote for best athlete. He set the record for points, 9126, back in 2018, beating Ashton Eaton's mark. The points don't tell me the story, though. His times and distances when he set the record ,over 2 days, are just crazy:
100m- 10.55, long jump- 25'7", high jump-6"9", pole vault-17'10", 400m-48.4, javelin-235'10"
just to name a few. And, again, they do this back-to-back days! In the recent World Championships, the Olympic champion, Damian Warner of Canada, might have beaten Mayer and the record, had not he injured himself in the 400m.
