Mary Slaney's indoor American record of 4:20.5 and Kalkaden Gezahegne's World Junior Record of 4:24.10 remain standing after the latest Nike Oregon Project run at the record books. Mary Cain won the women’s mile at the Boston University Terrier Invitational in 4:24.11. Cain was one one-hundredth of a second off the World Junior Record. 

Her time is now the seventh fastest performance in American history and 12th fastest on the all-time list. Cain is also now the third fastest American at the event behind Slaney and Regina Jacobs (via all-athletics.com).

Dartmouth senior Abbey D’Agostino was added to the race earlier in the week and made the most of her appearance by running 4:28 for second place. Her time is the third fastest all-time by a collegian.

These were the splits for the leaders:
208-meters at 31.5 seconds
400-meters at 64.1 seconds
600-meters at 1:37.2
800-meter at 2:10.5
1,000-meters at 2:42.5
1,400-meters at 3:50.4
1,600-meters at 4:24.11

The only Oregon Project member alive when Slaney set the record in 1982 was Treniere Moser, who was only a few months old at the time.

Moser was slated to run, but withdrew her name from the start list less than an hour before the race. In August, the U.S. Outdoor 1,500-meter champion withdrew from the IAAF World Championships with a hamstring strain. She returned to action with a second place finish at the Boston University’s Multi-Team Meet in 2:39.32. 

Flotrack site editor Mitch Kastoff previewed the action and converted the 4:20.5 mile to 1:57.69 for 800-meters and 4:00.99 for 1,500-meters, which was a tall order along with going through the 800-meter in 2:09.6 and 1,000-meters in 2:42. Kastoff also noted that Cain's winning time in Boston converts to 4:04.31 for 1500m. On Thursday, I debated with fellow staff writer Isaac Wood on whether Cain would be able to break the record.
