Incoming Oregon freshman Ashlee Moore got off to a fast start in the heptathlon at the IAFF World Junior Championships on Monday. Moore achieved a personal best in the 100 meter hurdles  — the first segment of the competition  — with a time of 13.59 and finished second to Netherlands heptathlon athlete Nadine Visser.

“I finally ran 13.5 so I’m really happy about that,” Moore said. “I definitely had a real good start.”

An eighth place finish in the high jump, the second event of the heptathlon, landed Moore in fifth heading into the afternoon session.

Despite the promising start, Moore was worried heading into the shot put — one of her weaker events.

“I definitely kind of lost my momentum in shot put, but It’s not my strongest event,” Moore said.

A throw of 9.87 meters in the shot put, and a time of 25.05 in the 200 meter dash, gave Moore a combined total of 3331 points after the first day and ranked her 11th in the 24-athlete field.

Great Britain’s Morgan Lake, who leads the heptathlon after the first day, broke the World Junior’s record in the high jump with a jump of 1.94 meters. Lake broke the previous record of 1.92 meters held by Sweden’s Carolina Kluft, who won the heptathlon gold medal in the 2004 Olympics, and Belgium’s Nafissatou Thiam.

“The high jump was a big surprise, getting a personal best and the junior record,” Lake said. “So, yeah, I’m really happy with the high jump.”

The field remains tight heading into the final day of the heptathlon. Moore trails Lake by 490 points and Visser, who finished in second after the first day, is behind by only 169 points.

“In the heptathlon anything is possible,” Visser said. “People can make mistakes.”
