Talking about their athletes, not their personal racing results.
AlSal has Rupp, arguably the GOAT of US distance running, two Olympic Medals, 10k area record, along with 5000i, 3000i, 2 milei ARs.
Additionally:
Mo Farah and his assortment of Gold Medals and ARs or previous ARs
Centro and his OG and 3:30
Cam Levins
Jordan Hasay ran her fastest times under him
Shannon Rowbury got a few medals with him and ran her best times with him
Suguru Osako got a NR with him in the marathon
Ritz ran his best times with him, including an AR in the 5000
He kinda ran Mary Cain into the ground though
Probably others I've forgotten
Schumacher:
Got Solinsky to sub 27 and 12:55
Simon Bairu got the Canadian 10k record
Teg got to sub 13
Mo Ahmed has a bronze medal and an array of NRs and the 5000m AR
Lomong sub 13
Centro ran 13 flat but appears injured a lot
Ryan Hill with a 7:30
Woody Kincaid sub 13
Jager 8 flat, 13:02, and Olympic Silver and WC Bronze
Jerry also has more success with women it appears:
Shalene Flanagan silver in the 10000m, a bunch of WMM podium placements, held/holds multiple ARs
Amy Cragg has a few medals and fast times
Houlihan with 3:54, and 14:23
Colleen Quigley with 4:03 and 8:21
Frerichs with a steeple AR and 14:50
Schweizer with a 3000m AR and 14:26, and 4:00
Problably still a few more
I'm gonna have to give it to Jerry. Tons of fast times for over a decade now from a ton of different people.
