Olivia Tauro ran 11.71 and 23.90 and made the 200m final at the 2005 World Youth Games having just turned 15. At the 2007 Youth Games, she ran 11.83 and 24.13 and didn’t make a final. At the 2008 World Juniors, she ran 24.09. She will be 20 this year, and her PBs are all at least 2 years old: 11.68 (fom 2007), 23.62 (from 2008) and 53.21 (from 2007). She now focuses on the 400m, where she always runs a devastating first 300m and then dies badly over the last 80m or so.
You can see her running in lane seven here: http://www.runnerstribe.com/event/main/video/id/236825-NSW-Track-and-Field-Championships-2010/vid/322754-NSW-Champs-2010-Women-400
Jacinta Doyle had her best year in 2007, got slower in 2008 and doesn’t seem to be competing anymore now.
Unfortunately these types of stories are all too common amongst young Australian sprint talents.
