After missing the 2024 Boston Marathon following the Olympic marathon trials, Mantz is expected to make some noise on April 21 as the top U.S. men’s distance runner. The winner of the 2024 Olympic marathon trials, Mantz has routinely etched his name in the record books over the last few years.

It wasn’t the best day for O’Connor Monday at the 129th Boston Marathon but he still finished in 2 hours, 18 minutes and 22 seconds, a few minutes slower than last year, and he was the top finisher from Connecticut. He was 42nd overall and the 24th American.
