Olympic champion Keely Hodgkinson safely negotiated the heats of the 800m in Birmingham on Tuesday as she seeks a third consecutive European title.
Home favourite Hodgkinson, who previously won continental crowns in Munich in 2022 and Rome two years ago, timed 1min 57.28sec to win her heat.
"The championship is a fresh start. It felt good. The standard has gone up. That was one minute 57 in the heats!" said Hodgkinson.
"We are dragging the best out of each other and the standard keeps getting higher and higher, but it brings out the best in me."
Hodgkinson added: "I felt really good. I'm so glad the race was a bit quicker. I felt it was at a similar rhythm to when I train. I'm glad because sometimes a slower race can feel awful.
"I just got back from Portugal so I feel great. I got a nice tan there and had some relaxation time, which is always needed. That has prepared me to be here today."
World championships finalist Eloisa Coiro of Italy set a national record of 1:57.56 in finishing second behind the Briton, while three-time European silver medallist Renelle Lamote of France could only finish fifth but qualified as one of the fastest finishers outside the automatic spots.
Also qualifying with ease for Thursday's semi-finals, with the final a day later, was Switzerland's Audrey Werro, who won her heat in 1:57.83.
Werro this season clocked the third fastest time ever in the two-lap race and the rivalry between her and Hodgkinson has set the 800m as one of the must-see races at the Birmingham Euros.
The pair last met at the Stockholm Diamond League in June, when Werro outpaced Hodgkinson, timing 1:53.98 for the victory to become the first woman to dip under 1:54 since 1983.
The Swiss runner then bettered that with a blistering 1:53.80 to win at the Paris Diamond League.
Hodgkinson improved her own British record to 1:54.33 behind Werro in Stockholm. She then went on to win the London Diamond League.
Hodgkinson had broken the 24-year-old world indoor record in Lievin in February before claiming a first world indoor title in March.
"I don't really care about the noise about me," said Hodgkinson. "I haven't got time for that. I just focus on myself and do what I can do."
Never to be ruled out is Dutchwoman Femke Broeders-Bol, the former two-time world 400m hurdles champion who has transitioned into a 800m specialist.
