The two-time Olympic cyclist was able to achieve a distance of 47.791 kilometres at the close of her hour ride at the Avantidrome in Cambridge in her home country.

It proved to be 909 metres further than the previous world’s best at sea level, which was set by Australia’s Bridie O’Donnell in Adelaide last year.

The 31-year-old was narrowly adrift of the 47.980km mark of the United States’ Evelyn Stevens.

Stevens mark was set at the Colorado Springs Olympic Training Center Velodrome, which is located at 6,000 feet above sea level, with the altitude aiding the effort.

“I am so happy it’s over, it was such a challenge,” said Nielsen.

“I am stoked and I am satisfied, I know I gave it all I can.

“I knew it was realistic to get the sea-level mark.

“It came down to counting the laps and at one stage I was counting half laps.

“I’d love to give it another shot, at this stage I am glad it’s over.

“There were feelings that I had to overcome and I think the crowd helped me get through in the end.”

Nielsen’s attempt was the fifth by a woman since the International Cycling Union (UCI) ruling that the record could be broken on an aerodynamic bike in May 2014.

She will now seek to earn selection for the UCI Road World Championships in the time trial.

Nielsen will then turn her attempts to attempting to gain selection for the Gold Coast 2018 Commonwealth Games.
