19-year-old Barbora Seemanova continued her incredible run of improvement in the women’s 400 freestyle during the first prelim session at the World Championships in Gwangju, setting a new Czech National Record in a time of 4:09.73.
Entering the 2019 calendar year with a personal best of 4:21.36, Seemanova has now reset it six times. After getting down to a 4:14.38 in March, she clocked a 4:13.29 at the Canet stop of the Mare Nostrum Tour in June, and then finally got under the National Record a few days later in Barcelona. She touched in 4:13.10, slipping under Barbora Zavadova‘s 2014 mark of 4:13.18.
She brought it down even further a few days later at the Czech Championships, going 4:11.10, and now finds herself under 4:10.
