Stanford senior David Nolan has broken the NCAA, American, and U.S. Open Records in the 200 yard IM on Thursday at the 2015 Pac-12 Conference Championship meet.

Nolan swam a 1:40.07, which snuck just under the 1:40.08 that Ryan Lochte did in 2007 at Winter Nationals – the old fastest-ever result in this event.

The swim also broke the 2009 NCAA Record done by Bradley Ally, then at the University of Florida, in 1:40.49.

Nolan came out of high school with one of the most unbelievable National High School Records in history, with a 1:41.39. In his first three seasons at Stanford, he only improved that by .18 seconds until his explosion on Thursday evening.

Comparative splits:

Nolan ’15: 21.96/24.95/29.05/24.11 = 1:40.07

Lochte ’07: 22.00/24.24/29.28/24.56 = 1:40.08

Ally ’09: 21.46/24.42/29.86/24.75 = 1:40.49

Nolan HS: 22.07/24.92/29.76/24.64 – 1:41.39

Where Nolan’s race has really improved since high school has been on the breaststroke leg. That’s shown when he’s dabbled in the race individually over the past couple of seasons, and really showed up in this race.
