The first day of the York Region Athletic Association track and field championships Tuesday at York University turned out to be a record-setting outing for the Stouffville District Secondary School Spartans team.

Two members of the Spartans contingent rewrote the YRAA record books while several others etched their names in the school’s track and field annals.

Natalie Geiger set a region and school record in the senior girls’ 400 metres when she was first to cross the finish line in a time of 55.57 seconds.

The Grade 12 student also won gold in the 100m in a time of 12.43.

Another regional record was established by Dan Coskun in the senior boys’ shot put as he won the event with a toss of 14.22m.

Coskun also finished second in the javelin, but smashed the prior school mark by almost six metres with a toss of 48.60m.

Other school marks were set by Kate Schlussler in the junior girls’ 80m low hurdles, who won the race in a time of 12.95.

Among boys, Liam Mitro set a school mark in the midget boys’ 400m, winning the race in a time of 55.54.
