Tributes have poured in for a young businesswoman who died after a head-on collision between her bicycle and a car in Sydney's south.
Casey Kinnaird, 35, died on Tuesday, four days after she collided with the car at Waterfall on Saturday.
It is understood she swerved onto the opposite side of the road and hit the oncoming vehicle while training for an upcoming Ironman challenge.
Ms Kinnaird suffered a stroke and was placed in an induced coma before her family decided to turn off her life support.
"If we saved her life then she would be in a vegetative state for the rest of her life," Ms Kinnaird's younger sister, Jevada, told Fairfax.
"We know she would not have wanted to be in a vegetative state."
Originally from New Zealand, Ms Kinnaird moved to Sydney as a teenager and lived in Cronulla with her husband.
She founded her own financial services company, Bespoke Advisory Services, and was an ambassador for female entrepreneurs after being named a NSW Crusader by the League of Extraordinary Women, which aims to support young women in business.
The 35-year-old competed in her first New Zealand Taupo Ironman event last year and was also involved in charity work in Cambodia.
Her father, David Kinnaird, said he did not blame anyone for his daughter's death and he issued a plea for cyclists to take care on the road.
