Calabar won the boys 4x400m race in record style, completing the High School Championship of America triple at the 124th Penn Relays, on Saturday (28 April).
Their time of 3:03.79 is a new high school world record.
This historic performance capped a successful day and weekend by Calabar in Philadelphia, conforming in glorious uniformity with victories in the 4×1 and 4×8 relay events.
They became the first high school team to win the triple since 1949.
Malik James-King led off with a 47.6 split to Anthony Carpenter 45.5, then Shemar Chambers ran for 45.8 seconds, to hand off to Christopher Taylor who closed in 44.84 secs.
They dominated from the gun and left Taylor the chore of chasing history, which he effortlessly did, leading three teams, all from Jamaica, under 3:10 mins, including Petersfield (3:09.50) and Kingston College (3:09.60).
Of the seven other Jamaican high schools that qualified and competed in the championship of America finals, Jamaica College finished just off the podium in 3:10.29, Holmwood Tech came fifth in 3:11.35, sixth was Edwin Allen in 3:13.37 and ninth was Rhodes Hall in 3:22.44.
With these wins Calabar earned its ninth 4x400m and 4x100m titles, tying for the most in the 4×100 and extending its lead in the 4x400m, in the process cementing itself as one of the greatest Penn dynasties ever.
They have also won the 4x800m relays, three times.
The 4x400m was a Wall of Fame Event in Honor of the 1990 Calabar High School team (Chris Gallimore, Everton Rhoden, Daniel England and Hugh Powell).
