Sally Pearson can win an Olympic medal as a 33-year-old in Tokyo according to coach Craig Hilliard.

Usain Bolt's teammates have accused organisers of contributing to the retiring superstar's dramatic collapse during his farewell to competition at the world championships.

Eight years after she won an unexpected and premature world gold as a 21-year-old, Dani Stevens has won a world silver medal in a fashion almost as unexpected her world gold.

After three lost years ruined by injury, Sally Pearson is world champion again.

A bold plan nearly paid off for Aussie Pat Tiernan in the 5000m final. His tactic might have helped consign the great distance running great Mo Farah to silver.

Sally Pearson's second world championship gold has elevated her to the best Australian track athlete of the modern era, according to Australia's head coach.

The world's most glorious athlete, Usain Bolt, finished his last race in the most inglorious fashion walking across the finish line.

Leading the steeplechase, Kenya's Beatrice Chepkoech forgot to peel off for the water jump and just went sailing on by.

She could see she had lost her Olympic final before she had even begun.

Sally Pearson is poised for one of the great comebacks after recovering from years of injury to be the fastest qualifier into the world championship hurdles final.

It's easy to justify the eruption of boos that accompanied Gatlin's spoiling of the Bolt fairytale. But it's still wrong.

Two weeks ago Luke Mathews sacked his coach and struck out on his own, fearing he would bomb again as he did in Rio last year. Today in London he won his heat and was the fastest qualifier in the men's 1500m.

The rest of the world should be worried. They are on notice that Sally is back, the old Sally is back, Australia's head coach has warned.

In sheeting London rain, three Aussies delivered confident strong performances to make finals at the World Athletics Championships.

This was the loneliest race. In quarantine one day Botswana's Isaac Makwala was given the all clear by doctors to return to competition and was allowed to race the clock in a race on his own to qualify for the semi finals in the mens 200m on an unusual night on the track.

Kelsey-Lee Roberts threw well short of her personal best at the world championship final.
