The 23-year-old has been picked for the 20 kilometres event after Jared Tallent, her sibling and coach, was chosen for the men's 50km event in January.

Rachel Tallent's selection comes following her victory at the Oceania and Australian 20km Race Walking Championship in Adelaide.

She worked her way through the field and took the lead in the final stages, eventually claiming a surprise victory in 1 hour 31min 33sec.

"Going in I didn’t really expect to win, I just wanted to finish in the top three to be considered for Olympic selection,” she said.

"I wanted the last lap to last forever."

Jarred boasts significant Olympic pedigree having won a silver medal in the 50km walk at London 2012, adding to the silver and bronze medals he claimed at Beijing 2008.

He finished second in London behind convicted doping cheat Sergey Kirdyapkin of Russia, who was banned for three years and two months, backdated to October 2012.

That allowed him to keep his Olympic gold but 31-year-old Tallent has regularly spoken about the issue and describes his own Rio selection as a shot at "redemption".

“I really like being my brother’s little sister," said Rachel Tallent.

“He inspired me to be a race walker, and to one day make the Olympics like him.

“To be able to go to Rio with him as my coach, brother and my friend is the best feeling in the world.”

Australia have also selected 23-year-old men's race walker Dane Bird-Smith, who will compete at 20km.

He also won in Adelaide, clocking a personal best of 1:20.03, and will follow in the footsteps of his Moscow 1980 Olympian father David Smith.

"Dad was so, so proud," said Bird-Smith.

"I've never seen him as proud as that, that beaming face.”
