Josh Lampron of Mansfield, Mass. ran 3:45.74 for 1,500 meters Saturday night in the New Balance Boston Twilight Series at Bentley College.
Lampron competed unattached and placed sixth in a race with older runners. His time is a US#1 for 2012 by more than five seconds and it also moves him to No. 18 all-time in the event. He ran 3:50s on three occasions last spring and was the New Balance Nationals Outdoor mile champ in 4:05.99, but relative to 2012 the performance seemed to come out of the blue: His previous races this spring included a 9:43 two-mile and a 4:24 mile.
Meanwhile, Cayla Hatton from Phillips Academy in Andover, Mass., also competed unattached and placed fourth in 4:18.65. That is US#2 this spring and No. 14 all-time. Hatton has raced sparingly and independent of her high school and also has US#1 times this spring in the 10,000 and 5,000.
According to Track and Field News, those performances rank Lampron No. 3 all-time in Massachusetts behind Jonathon Riley (3:43.18) and Victor Gras (3:45.19). Hatton moves ahead of Ari Lambie to No. 2 behind Olympic bronze medalist Lynn Jennings (4:18.06).
