Catriona Bisset has continued her remarkable breakout season by consigning the 43-year-old Australian women's 800m track record to the annals of history.
Bisset, 25, stormed home to finished second behind local star Lynsey Sharp on day two of the London Diamond League meet in a time of one minute 58.78 seconds.
The previous Australian mark of 1:59.0 was set by Charlene Rendina way back in 1976.
"Lynsey felt me coming round and pushed me out onto lane two but that was great," said Bisset.
"I felt so strong, coming down the back straight.
"I feel like I still had a lot in me and it was nice to push it all the way."
Bisset first shot to prominence by winning the national 800m title in April, before dipping under the two-minute barrier for the first time a week later.
She has also won the Oceania and World University 800m titles in the past four weeks and shapes as one of Australia's best track hopes at the world championships in Doha beginning in late September.
"I knew I had that kind of race in me just because of the winning streak," she said.
"I knew if I had a quick pacemaker I could take some time off some my PB and I took exactly a second off."
Aussie athletics world in awe
Fellow Australian Morgan Mitchell also took full advantage of the quick 800m pace at the London Olympic Stadium to finish fifth in a personal-best time of 2:00.06, bettering the automatic qualifying mark for the Doha world titles in the process.
Promising Australian junior Carley Thomas was eighth in 2:01.01.
The only Australian track record older than Rendina's 800m time is Peter Norman's 200m mark of 20.06 seconds which dates all the way back to the final at the 1968 Mexico City Olympics.
In other Australian action in London on Sunday, Matthew Ramsden stripped five seconds off his PB for the mile and moved to seventh on the national alltime list after stopping the clock at 3:53.32.
Rio Olympics finalist Brooke Stratton was fourth in the women's long jump with a best of 6.64m.
I’m just happy Australia finally has an electronic time as its national record like all @iaaf records. Couldn’t have gone to a nicer girl. Well done Trina. Was a cracking run 👏🏻and lots more to come— Tamsyn Lewis Manou (@tamsynlewis) July 21, 2019
Wowee. @catrionabisset has just broken the Australian 800m record with 1:58.78. It was set 43 years ago by Charlene Rendina..... 43 years, imagine how many have tried in that time!!!— Richard Welsh (@WelshyKnows) July 21, 2019
The best thing about @catrionabisset 800m run was the excitement of @morganmitch2 waiting and watching for the result to come up and celebrating the record. Morgan ran a huge PB and just missed a sub 2mins. Good #painface on Bisset as well! pic.twitter.com/Iua5FdH0sZ— David Culbert (@Culbert_Report) July 21, 2019
It's gone!— Brian Roe (@Doctor_Roe) July 21, 2019
After 43 years, 4 months and 22 days Charlene Rendina will have to get used to no longer being the @AthsAust national record holder for 800metres.
She hands the reins to 2019 season sensation @catrionabisset who ran 1.58.78 in @Diamond_League in London overnight.
The 43-years and 143 day-old, second oldest Australian record, oldest Australian women's record of 1:59.0 by Charlene Rendina is broken by @catrionabisset clocking 1:58.78 over 800m.#LondonDL pic.twitter.com/PfDuHJtyYY— Athletics Australia (@AthsAust) July 21, 2019
