Evergreen Lisa Weightman will match the record of three all-time greats of Australian long-distance running when she contests a fourth Olympic marathon at the Tokyo Games.
Weightman, 42, is among a full complement of six Australians selected on Friday to tackle the Olympic marathons, which will be held in the northern city of Sapporo to avoid the forecast heat in the Japanese capital.
The diminutive Victorian also raced the 42.195km event at the 2008, 2012 and 2016 Games, with her best Olympic finish of 17th coming nine years ago in London.
The only other Australians to have contested four Olympic marathons are 1988 Olympic silver medallist Lisa Ondieki, 1983 world champion Robert de Castella and 1994 Commonwealth champ Steve Moneghetti.
"To join stars of our sport like Lisa Ondieki in being selected for a fourth Olympic marathon is a dream come true," Weightman said.
"I am extremely proud to have created this opportunity and with everything on my plate, with fulltime work, a mum in lockdown and an athlete, I've certainly built up the resilience I need to run my best in Sapporo."
Weightman will be joined on the women's start-line on August 7 by 44-year-old Olympic rookie Sinead Diver and Ellie Pashley.
The 32-year-old Pashley also qualified in the 10,000m but has made the marathon her priority.
Weightman, Diver and Pashley are ranked in the Australian all-time top eight.
The men's marathon squad includes Brett Robinson and Liam Adams, both competing at their second Olympics, and Games debutant Jack Rayner.
"Tokyo is finally around the corner and it's getting real," said Robinson, who made the 5000m final at the Rio Games.
"My training is starting to really ramp up and I'm excited for what's to come.
"The last four years, I've changed my focus from the track to the marathon, and the Olympics has been the big goal and the focus."
With 2012 Olympic champion Jared Tallent announcing his retirement earlier this year, Australia's only representative in the men's 50km walk will be Rhydian Cowley.
Rio Games bronze medallist Dane Bird-Smith and Jemima Montag were pre-selected last year to contest the 20km walks.
