In 2014 it was the Men's 4x800m record that went, and in 2015 it was the women's turn to set new all-time marks, this year in the Distance Medley Relay. New Balance USA's quartet of Sarah Brown, Mahogoney Jones, Megan Krumpoch and World Championships bronze medalist Brenda Martinez broke the tape in 10:42.57, shattering the record set by the University of Tennesse six years earlier (a team that Brown had herself anchored) by nearly eight seconds. Another world best came in the Women's 2000m, a rarely run discipline which saw Ethiopia's Dawit Seyaum establish a new indoor junior best. After miscounting laps in 2014, Jenny Simpson returned to finish the job and set a new American Record for two miles, winning comfortably in 9:18.35. Matthew Centrowitz won the men's 1000m in 2:17.00, breaking David Krummenacker's 13 year-old meet record and just missing the American Record, while Nick Willis won again in the Men's Mile, this time in 3:51.61, a time that bested both the meet record from 2005, as well as John Walker's New Zealand national record from 1981.
