Barbora Seemanová and Miroslav Knedla both set Czech national records at the European Aquatics Championships in Paris on Wednesday, advancing to the evening semi-finals with strong morning swims.
Seemanová lowered her own 100m butterfly record to 57.43 seconds, improving the mark she set in the same pool two years ago by seven-hundredths of a second. She won the opening heat and progressed as the third-fastest qualifier, behind only Belgium's Roos Vanotterdijk and Germany's Angelina Kohler, who both broke 57 seconds. Knedla trimmed his 50m backstroke national record to 24.19, finishing third behind two Russian neutrals.
Vanotterdijk, who won silver in the 50m butterfly final the previous day, topped the 100m butterfly heats in 56.76 seconds. Belgium's Lucas Henveaux also reached the 200m freestyle semi-finals with the fifth-fastest morning time of 1:46.10, narrowly missing his national record.
