Multiple rowing world champion Sarah Hawe was gearing up for Tokyo 2020 to be her first and last Olympic campaign.

However, the resulting closures and postponements have left the 32-year-old contemplating whether to carry on for Paris 2024.

Hawe said her immediate emotion about the Olympic postponement and closure of National Training Centre in Penrith was anger.

"I was livid that something which can't even be seen with the naked eye could derail my plans," she said.

"I had geared myself up for the 2020 international season, including hopefully making the Tokyo team, to be my last.

"Any time we did a testing erg I was happily thinking 'that's the last time I'll have to do one of those.' However, as most athletes know, once I had set myself the goal of the Olympics, I was hardly going to just stop there. So to be honest it was never a thought, option or consideration to quit."

Returning to her parents' home in Melbourne with an ergo machine from the NTC plus borrowed weights from the Victorian Institute of Sport, the Huon rower persuaded her father to build a temporary gym set-up in the garden.

Over the last month, Hawe has been replicating a traditional post-world championship training load which she said has enabled a troublesome shoulder injury to heal and led to a major change of mindset.

"Now that I'm in the swing of things I am loving being back home," she said in the Tasmanian Institute of Sport bulletin.

"I am really enjoying the increased freedom and autonomy that I have gained. I also really appreciate being able to train by myself - doing what I want, when I want - rather than in a large group.

"I have also been using this time to tailor sessions, specifically strength-based ones, to the areas that I believe I need more work on.

"You never know, now that I'm loving training this much, thoughts like 'well 2024 is only three years after Tokyo' have crossed my mind!"

Despite only breaking into the elite level of the sport aged 29, Hawe has been an integral member of the women's four which won two gold and a silver medal at the last three world championships.

She said she online Zoom sessions with fellow TIS athletes aided physical and mental wellbeing and hoped they would continue after the COVID-19 isolation.

"I am missing being in Tassie and jealous when I see people out cycling in the amazing land that it is," she added. "But rest assured I'll be back when this all blows over."
