Already in 2025, Ruthe has set a world record for the fastest 1500 (3:41.25), mile (4:01.72) and 3000 (7:56.18) ever run by someone at the age of 15 (he turns 16 on April 12). That being said, Ruthe tying his training mate Tanner is a shock as Tanner ran 3:51 in the mile for the win at BU on February 21 and has a 3:31 1500 pb from 2023. Race video embedded above.
