After graduating for the University of Birmingham, Weir has moved to Oregon to study for a master’s degree at Portland University, where she is part of the women’s athletics team.
She competed at her first event at the weekend – the Western Oregon University Sundowner – and stormed to victory.
Weir, who represented Great Britain at under-20 level, won by more than 20 seconds at Ash Creek Preserve.
Weir follows her City of Plymouth international colleague Poppy Tank in studying in America. Tank is at Utah University.
