Beadlescomb is 25 and was behind Kessler. Kessler will be 25 at the 2028 LA Olympics. Kessler's season opener at age 20 was 3:32. He was 1 second behind a very in form Cheruiyot. How many 3:32 guys can say they were a world class rock climber a couple years ago? It's actually the exact same number of Americans that have been the 1500m Olympic Champ in the last century.
Sleep on Kessler if you want. He's got just as much talent as Jim Ryun did. If you wanna talk about what's more impressive, I'm taking the guy who climbed rocks for 16 years, started running, then ran 3:34 2 years later. The guy that ran faster than Nuguse's collegiate record while he was still in high school. And the progression too: 4:08 junior year, 3:57i senior year opener, 3:40 outdoor opener, 1:49 2 weeks later, 3:34 2 weeks later.
