Former Te Kura O Tititea Mount Aspiring College student Ellesse Andrews has bagged her third medal of the Paris Olympics - a gold in the women's sprint cycling, her 'bonus' event.

It was Ellesses' second gold medal of the Games and New Zealand's 10th.

The 24-year-old said she felt like she was "living in a dream" following her gold medal ride, and was "so proud" of what she had achieved.

Ellesse faced off against German rider Lea Friedrich in the medal races late Sunday night NZT after twice beating Great Britain's Emma Finucane - the reigning world champion - in the semifinals.

Lea and Ellesse were closely matched. The German set a new world record of 10.029 seconds for the 200m flying lap during sprint qualifiers on Friday, while Ellesse was not far behind, with 10.108 seconds.

The gold medal race was a best-of-three format. Ellesse took the lead in the first race and never relinquished it, slicing home to beat Lea by 0.095 seconds.

She then started her second medal race sitting behind Lea, but raised the pace with two laps to go and blasted past the German for the win.

Going into the sprints, Ellesse already held two medals from the Paris Games - a silver in the women's team sprint relay and a gold in the women's keirin.

Getting through to the gold medal race was a huge result for Ellesse. Speaking earlier in the week, her coach and father Jon said the sprint was considered her "work-on" event for the Olympics.

"Ellesse is a really determined athlete, so she'll want to do well in the sprints. She's not quite as strong in the sprints," he said.

"She's still learning a lot in that space, and she loves the kierin. Like she actually loves the chaos of the kierin, which is kind of crazy because if you got two riders on the track, it's a lot simpler in terms of execution, but Ellesse finds that harder."

Ellesse said it had been a "massive week" at the Olympics.

"I'm just so proud of how I've managed to carry myself to the end of the competition."

She said Lea was an "amazing" opponent.

"I'm just telling myself, 'It's just one more race and leave it out on the track'. I wanted to finish that race knowing I had absolutely emptied the tank, which I did."

Ellesse has been sprinting since she was 19, and riding a track bike since she was 13 or 14.

"It's been a 10-year dream to be here and not one that I always thought was possible.

"In your younger years, you never know where you're going to end up in your career - but I really started chasing that, probably around 16 years old, and here we are today."

She said it was a "real surprise" to end up in the medal race for the sprints, as it was not her strongest discipline.

"I do enjoy this event, but it is really tough. It is over three days and then having raced the keirin beforehand, a few little restless nights of sleep it is really tough to come out and perform mentally and physically."

She said she "never would have expected" to win three medals - two of them gold - in Paris.

"It's very overwhelming, but I'm very proud to have walked away with such results."

Shortly after Ellesse won gold, fellow cyclist Ally Wollaston claimed the bronze in the women's omnium - the final event of the Paris Games.
