In her first major race since she won last year’s Meet of Champions 100, Williamstown senior Bria Mack edged Delsea senior Cecelia Gerstenbacher by 4-100ths of a second Thursday to win a loaded Gloucester County Meet 100 over a loaded field at Delsea.
Mack ran 12.01 to Gerstenbacher’s 12.05, with Meet of Champions runner-up Iyana Kollock of Our Lady of Mercy third in 12.44.
The 12.05 was a PR for Gerstenbacher, who had run 12.09 twice — at the Tri-County meet and sectionals in 2015.
The times are No. 2 and 3 in South Jersey so far this year, behind an 11.95 by Aliyah Taylor of Rancocas Valley last month at the Lenape Invitational.
Taylor hasn’t raced since pulling a hamstring in the Penn Relays 4-by-400 but is expected back for the Burlington County Open a week from Saturday.
On Thursday at Delsea, Mack also ran a 400 leg on Williamstown’s third-place 4-by-4. Gerstenbacher ran 24.92 to win the 200 and 58.42 to place second in the 400 behind teammate Toni Glatz, who ran 57.62.
Gerstenbacher’s 58.42 is another PR, breaking her previous mark of 58.50 set indoors at last year’s states in the Bubble.
She’s also undefeated this year at 200 meters and ranked No. 2 in South Jersey at 24.84, 1-100th of a second behind RV’s Taylor.
Meanwhile, Glatz’s 57.62 is also a PR, breaking her previous mark of 58.25 set this past winter at the Bubble at indoor Meet of Champions.
