Lizzie Williams (Orica-AIS) soloed to win Stage 3 of the Santos Women's Tour in a testing day in the Barossa Valley.
She attacked with only a few kilometres to go before gaining a critical lead of 30 seconds on a chasing group of six.
Tiffany Cromwell (CANYON//SRAM on loan to SASI) launched repeated attempts to get across but with two of Williams' Orica-AIS teammates behind her, every move was covered.
Earlier, Williams' teammate Amanda Spratt herself attacked a reduced peloton and was closely followed by the group of six that remained together until Williams's attack.
She started the fourth and final lap of the 25.2 Lyndoch circuit with a 30 second lead on the chasing group of Shelley Olds (Cylance), Dani King (Wiggle-High5), Katrin Garfoot and Lizzie Williams (Orica-AIS), Lauren Kitchen (Hitech Products), plus Cromwell.
Spratt's move was the perfect set up for Williams, falling back into the group once caught. Garfoot and Kitchen followed down the straight for second and third.
“It was hot out there!,” Williams said. “We had strong girls out there and we knew we could get the numbers. (Amanda Spratt) Spratty was just a workhorse out there, dangling off the front like a rabbit.
“It allowed me to be able to sit on the whole time and that’s why ultimately I had the energy to go with about four kilometres to go, and that’s teamwork!”
The tour is set to go down to the wire, as Garfoot, Kitchen, Olds and King are all locked on the same time.
King also controls the mountain classification jersey with 16 points, while Lauretta Hanson (Total Rush) has a nine point lead over Annette Edmondson (Wiggle High5) in the sprint category.
With significant headwinds at the start/finish line and soaring temperatures circuit wide, the peloton fell apart. At one point, there was concern many riders would not make the time cut.
