Abbie Wood made her first 200IM journey inside 2:09 to book an individual berth at Paris 2024 in 2:08.91.
The 2021 European silver medallist sliced 0.24secs from her previous best of 2:09.15 from the Tokyo Olympics where she finished fourth.
It was well within the qualification time of 2:10.62.
Wood, coached by Dave Hemmings at Loughborough, had spoken to Swimming World before the final of the all-or-nothing nature of the trials where there are no second chances.
“Probably a little more nervous but I always know it’s for the right reasons.
“You’ve only got one day at the Olympics to do it so if you can’t do it on the day here, you’re probably not going to be able to do it in Paris in front of a massive crowd.
“So for me I think it’s a good exercise; obviously the nerves are there but I think I’m definitely more used to it because it’s always been that way since I’ve been swimming at British Champs.
“So it’s nerve-wracking but if I can’t do it at champs then I definitely won’t be able to put in my best performance at the Olympics so I’m okay with it.”
Ultimately, Wood stood up and performed on the day when it mattered to finish ahead of Freya Colbert (2:10.46) and Katie Shanahan (2:11.39).
