Is Conner Mantz ready to OBLITERATE the American marathon record at the 2025 Chicago Marathon?

/Only three non-African-born men have ever broken 2:05 and two of them have been accused of PEDs. Mantz, who has already set an American record in the half (59:17) and run 2:05:08 on Boston's non-record-eligible course in 2025, is looking to join the club on Sunday. *MB: How fast will Conner Mantz run in Chicago? The AR is 2:05:38. Might he DESTROY that & run in the 2:03s?
