Jackson Spencer Shatters 3200m Record 

For years, the boys' 3200m has been the main event at the Arcadia Invitational, and after many fans felt underwhelmed by last year's race, the boys this year were determined to bring the mystique back. Jackson Spencer from Herriman (UT) took it upon himself to do exactly that with the help of Belen Jesuit's (FL) Marcelo Mantecon, who pushed him to the limit. 

Spencer closed in 56 seconds to shatter the meet record and run the fastest 3200m in high school history, 8:31.50. He led 29 boys in the invitational race under the 9-minute barrier and was 1 of 55 boys who broke 9 minutes at Arcadia this year.
