Lengthy Sports Illustrated article. First mention of metric about halfway down the page:
https://www.si.com/olympics/2023/11/03/former-olympic-bobsledder-steve-mesler-running-new-york-city-marathon

I'm unsure just what comment to make on this. I expected an anti-metric article after this snippet:

Initially, Mesler balked. He couldn’t remember the last time he ran a kilometer—he uses Canada’s preferred metric system throughout the interview—and had never traversed more than eight kilometers in one day in the rest of his life.

They then went on to use metric exclusively without conversion for the rest of the article, starting in the next paragraph:

Figuring he’d say no, Mesler entered a 10K race in April, just to see whether he could finish one. He did. In June, he tried a 12K and finished that one, too. The next weekend, he entered a 15K and completed it. Then, on one random training day a few weeks later, he reached the halfway point of his goal that afternoon, didn’t feel tired and decided to keep chugging. He didn’t stop until completing 21 kilometers, or roughly half a marathon.

Reality is that long distance road running is metric. Thanks SI for using the SI.
