Laura Muir smashed the British mile record as she stormed to victory at the Muller Indoor Grand Prix.
The Scot, a triple European champion, broke Kirsty Wade’s 31-year-old indoor record by five seconds in four minutes 18.75 seconds in Birmingham on Saturday.
She is preparing to defend her 1500m and 3000m titles at the European Indoor Championships on her home track in Glasgow next month.
Muir, already guaranteed a place on the British squad, now holds six UK records and clocked the third fastest indoor mile of all time.
“It’s pretty special, having come so close to the mile one outdoors it’s nice to nail it indoors,” said the 25-year-old. “It’s always special to get one, especially one which has stood such a long time and from an iconic runner as Kirsty.
“To run one of the fastest runs ever, a British record and a win in your final race before the championships is perfect. I’m really happy and confident.
“I’m at the stage where I’m just so confident and relaxed in my ability and with that I run better. There’s no questions over my ability. It’s about executing it on the day and I’m doing better and better at that.”
Wade’s mark of four minutes 23.88 seconds had stood since 1988.
Reece Prescod finished second in 6.53secs in the 60m behind China’s Bingtian Su.
The 22-year-old, who won 100m European silver last year, is skipping Glasgow as he prioritises the World Championships later this year.
He added: “I think this will silence the people who are trying to put me down about my start. I am really happy with that.”
Only Prescod and CJ Ujah have hit the indoor qualifying time of 6.60s with the British squad for Glasgow announced on Sunday.
Defending European Indoor champion Richard Kilty came fifth and, with the 29-year-old unlikely to be selected, questioned why British Athletics set the qualifying time so high.
There remains a possibility British Athletics will not select any male sprinter.
“I think there are only a handful of people in Europe who have run the British Athletics standard,” said Kilty, who ran 6.64s, having battled Achilles and foot problems last year.
“I was given clear instructions I had to run the standard and beat everyone who beat me last week.
“I beat everyone who beat me last week at the trials but I fell just short of the standard. I don’t know. I guess it’s what they want to do. I feel so confident I can get better if I was in Glasgow.
“Not to blow my own trumpet, but if they have to have faith in someone, I can go there and run much faster.”
Asha Philip finished second in the women’s 60m behind double Olympic champion Elaine Thompson.
Holly Bradshaw missed out on a British record in the pole vault but took victory with a clearance of 4.81m, beating Olympic champion Katerina Stefanidi, who came fourth.
World Indoor Samuel Tefera champion set a new world indoor record in the 1500m with a time of three minutes 31.04 seconds.
