Celia Sullohern will defend her Fernleigh 15 title later this month fresh from scoring a silver medal at the inaugural Commonwealth Half Marathon Championships.
The 26-year-old will contest the Hunter event on October 21 after improving her personal best time by six minutes over the 21.1 kilometre distance in Cardiff, Wales, on Sunday night (AEST).
Sullohern, coached by Newcastle Olympian Scott Westcott, stopped the clock at one hour, 11 minutes and four seconds to finish in between Ugandan pair Juliet Chekwel (1:09:45) and Doreen Chesang (1:11:10).
It was the 13th fastest half-marathon time recorded by an Australian woman.
Sullohern’s previous mark of 1:17:26 was set in Sydney in 2012.
In the space of six months, from October last year to April this year, the former University of Newcastle student bettered her personal bests for marathon (2:29:27), 5000m (15:34.42) and 10,000m (31:50.75).
This performance came a week after winning the Melbourne Marathon.
