Katarina Johnson-Thompson set a new British record in securing her first major senior title with pentathlon gold at the European Indoor Championships in Prague, but she couldn't help but think it should have been even better.
The 22-year-old ran a personal best of 8.18 seconds in the 60m hurdles and cleared 1.95m in the high jump to lead on 2,259 points after two events.
A 12.35m throw in the shot put dropped her to second but a 6.89m leap won the long jump and an 800m time 2:12.78 minutes set a new British best as ended up with a Championship record score of 5000.
This broke Jessica Ennis-Hill's record of 4,965 and Johnson-Thompson became just the second athlete to score 5,000 points in the pentathlon.
However, she finished 13 points behind Ukrainian Nataliya Dobrynska's three-year-old world record, having required a run of 2:11.86 in the 800m to break it.
"This is a huge breakthrough," she said. "But I am full of regret from the 800m.
"I thought I could easily run that time and maybe took it for granted. It could've been a different story. I should've been able to do that."
Meanwhile, 17-year-old Morgan Lake sat third in the pentathlon after recording a personal of 8.81 seconds in the 60m hurdles, however she dropped back to sixth after the shot put.
In the end Lake finished up in ninth place but she had the consolation of breaking Johnson-Thompson's British junior record as she finished on 4527 points.
There was more for Great Britain to celebrate on day one in the Czech Republic as Lucy Hatton and Serita Solomon won silver and third in the 60m hurdles.
Both posted personal bests – Hatton coming home in 7.90 seconds while Solomon finished in 7.93 – but neither could get the better of eventual winner Alina Talay of Belarus, who triumphed in 7.85.
Meanwhile, captain Lawrence Clarke finished fifth in the 60m hurdles final behind a French one-two-three led by Pascal Martinot-Lagarde.
Jenny Meadows reached the 800m semi-final by winning her heat in 2:02.59 minutes and in the women's 400m 20-year-old Seren Bundy-Davies, who leads the European rankings, came through a photo-finish to reach her showpiece.
