The long-jump board boomed when Felecia Majors stepped on it, a sound that made many of the spectators who were focusing on the track whip their heads toward the corner of the infield.

The boom triggered the looks. The mark made everybody gasp.

Majors was breathtaking in the long jump Saturday at the PR Holiday Invitational in Landover. On her first attempt, the speedy South County senior exploded down the runway before launching herself perfectly off the board and 19 feet 11 inches into the pit. That distance broke the three-year-old meet record by almost two feet and is the No. 1 mark in the country this season.

About 1,300 athletes from 48 schools in Virginia, Maryland and the District competed Saturday at Prince George’s Sports & Learning Complex and most of them weren’t expecting anything spectacular. For most, it was simply a matter of lifting the lid off their seasons and testing their fitness.

Majors, the two-time defending All-Met Athlete of the Year, initially had less-than-lofty expectations. She didn’t imagine landing so close to 20 feet and having two jumps of longer than 19 feet. At least not this soon.

“I thought I was going to start slow and build. I guess I can just go,” said Majors, a multi-event star who committed to Tennessee last week.

Mustaqeem Williams was the meet’s standout male performer. The Forest Park junior All-Met tweaked his hamstring at practice last week but was still strong enough to capture the 55-meter dash (6.48 seconds) and the 300 (35.41) before anchoring the Bruins’ 4x200 relay team that won easily over Midlothian in 1 minute 31.74 seconds.

Chantilly senior Kendall Cowne was a double winner, using a big move at the bell to win a thrilling 1,600 meters over Georgetown Visitation sophomore Emily Kaplan in a meet-record 5:07.52.

A few hours later, Cowne returned in the 1,000 and used another surge at the bell to outrun Midlothian’s Tessa Riley to the line and cross in 3:01.45.

Bishop McNamara senior Brielyn Rogers won the triple jump with a meet-record 39-4.75.

Woodbridge senior Olivia Coopwood won the 55 hurdles (8.65) shortly before helping the Vikings win the 4x200 relay over Dunbar in a meet-record 1:43.92.

Oakton senior Lucas Wratschko was the boys’ pole vault winner with a meet-record 14-6.
