After her championship season on the track, Caitlin Collier has two more trophies in sight this weekend.

The Bolles School senior and Stanford signee races for national titles at the USA Track and Field junior outdoor championships in Bloomington, Ind.

Collier, whose 800-meter time of 2:00.85 last month moved her into the world top 25 for the season, will race in the opening round of the women's 800 Friday. She's scheduled to compete in the final Saturday, followed by the 1,500 meters Sunday.

In addition, six more Northeast Florida high school athletes will challenge a field of leading prep competitors this weekend at the New Balance Nationals Outdoor in Greensboro, N.C.

Thousands of elite competitors from around the country will compete at Aggie Stadium in a three-day meet, among the nation's largest youth track and field events.

Creekside's Abby Thorpe has the heaviest workload, beginning Friday in the heptathlon. Thorpe's weekend begins at 1:20 p.m. Friday with the 100-meter hurdles and continues through the high jump, shot put, 200 meters, long jump, javelin throw and 800 meters.

Thorpe's Creekside teammate Makhaila Mills will race both girls sprint events, Bishop Snyder's three-time jump champion Semaj McGhee competes in the girls triple jump and Episcopal's Caroline Johnston is entered in the girls long jump and triple jump.

Bolles sophomore Laine Roberts is entered in the emerging elite division of the girls pole vault and Providence's Madison Murray combines two sharply different events, the girls high jump and javelin throw.
