Casey Clinger smashes American 25k record - 2nd professional race.

Just out of college and pushing age 40! Impressive.

Do some research and you learn he is 26 & went to BYU

60:21 HM equivalent based on a random conversion calculator online

Yes, it's a soft AF record

a decade in college. the greatest college runner of all time

Cool - now let’s try it again without the bouncy shoes. Something tells me we won’t however.

Looking good for Clinger and Klecker. But I went to check the all-time list… and someone split 1:11 on the way to a 2:01. We have a long way to go.

Considering that it’s Clinger’s first time racing further than 10k, and that he demolished Klecker and Bor over the last 1.5 miles and that he is now training with Mantz and Young, I think his future in the marathon is bright. Good luck Casey, I hope to see 3 BYU alumni on the 2028 US Olympic Marathon Team.

For comparison, Mantz/Young split 1:13:37 through 25k at Boston

He took two years off in Japan serving a mission and has been working a masters degree. Married and has a child. Pro runner. I think he has done a lot with himself

lol our half record was 59:40s until a couple months ago. for how little a 25k is run, this is probably at least as "impressive"

and by at least as impressive, I mean NEITHER ARE IMPRESSIVE

edit: i should clarify that I think it's an excellent result for Clinger at this stage in his very early pro career.

just not impressive when looked at in the context of a record.

Most guys are retired or thinking of retiring when they’re in their 30s. Klinger is just getting started.

Casey Clinger jokes never get old. Now HE on the other hand...

Reminds me of the meme where the fat guy is critiquing hot girls.

No they didn’t

do some more research, he served 2 years of missionary work in 2019/2020

2:02 marathon pace for 60% of 42.2 km.

Really stoked. I know he had been planning to run marathons after going pro. But after the Ten, I was concerned he'd try to focus on track and delay his move to the marathon. After making 18.5k in 8 days though I think it's starting to really make sense for him financially, becoming an AR holder, and racing a distance as long as 25k. I would be really excited to see him in a marathon potentially this fall.

just got back from doing some research. he graduated high school in 2017 and was still running for BYU as recently as march 29th, 2025
