Jacob, 13 on Saturday, will compete in the Australian cross-country championships in Albany, Western Australia, in August.

The Hamilton and Alexandra College student won the under 14 athlete with a disability class at the Athletics Victoria all schools cross-country championships on Saturday. It was his third straight title.

Jacob, who had his foot amputated at age seven after a rider mower accident on his family’s farm, ran three kilometres in 15.27.

His father Trevor said it was a gruelling course and the time was not Jacob’s personal best.

“It was a really difficult track — a steep hill into a headwind twice,” he said. “It knocked everyone’s times.”

Jacob will soon test out a new running blade — the first of its kind in Australia.

Trevor said it was unlikely Jacob, a South West Academy of Sport athlete, would be ready to use it at the national championships.

Jacob does running training twice a week and also plays football for Penshurst’s under 16 side.
