Charlotte Bonnet claimed her fourth victory and second national record at the French Short Course Championships on the penultimate night of competition.
The 27-year-old won the 50m breaststroke and 200m individual medley finals on the opening night before knocking 0.26 seconds off her own national mark in the 100m breaststroke on day two.
On Saturday, the third night of competition, she then broke the 200m record, of two minutes 21.55 seconds which was set by Sophie de Ronchi in December 2008, with a new landmark time of 2:21.34.
“This French record is really pleasing as it has stood for over ten years,” she said.
“It was close to my heart and to get there with such a beautiful time I think is really cool.”
Bonnet now holds the French short course records in the 50m (29.98), 100m (1:05.03) and 200m (2:21.55) breaststroke events.
Maxime Grousset continued his impressive form in Chartres by adding the 200m freestyle title to the 100m individual medley and 50m freestyle victories on the previous two evenings.
His latest success, secured in 1:42.09, saw him finish ahead of Roman Fuchs (1:43.16) and Wissam-Amazigh Yebba (1:43.60).
Elsewhere, Melanie Henique added the 50m freestyle title to her 50m butterfly gold, while Pauline Mahieu beat Analia Pigree to gold in the 100m backstroke final.
“I really wanted to win as my last one was back in 2015,” said Mahieu. “It’s not easy but I knew I’d get there one day.”
There were also victories for Carl Aitkaci (100m breaststroke), Emilien Mattenet (400m IM), Liou Ressencourt (200m butterfly), Thomas Piron (50m butterfly) and Maud Rodriguez (800m freestyle).
