Jenny Meadows broke the British 800metres indoor record belonging to double Olympic champion Dame Kelly Holmes at the Birmingham NIA.
Meadows clocked a time of one minute and 59.11 seconds at the Aviva Grand Prix, taking a tenth of a second off the mark set by Holmes in Belgium in 2003, to complete her preparations for the World Indoor Championships in perfect style.
The World Championship bronze medallist took advantage of some perfect pacemaking at the National Indoor Arena, the 28-year-old taking over the lead just after halfway and powering to victory to claim a bonus of 5,000 US dollars (£3,200).
Meadows, who also collected another $1,500 (£970) for the performance of the day, said: "It's amazing. I knew I was in really good shape from last week but then you look at the record, someone like Dame Kelly Holmes owns it and you think I've got no right to try to target that.
"Kelly didn't run an awful lot indoors but it's still a fantastic time so I'm very, very honoured and thrilled to get that time.
"When Kelly did the double gold in Athens I was still running 400m and only decided that winter to move to the 800m. I knew I didn't have the basic speed to be world-class at 400m and when you see a British athlete win at a global event it makes you think maybe I've got a chance.
"She definitely was a huge role model for me."
Meadows also revealed that the prize money will come in handy.
"Trevor (her coach and husband) is going part-time in his job from April 1 so he can devote more time to the training group so that will definitely help," she added.
World champion Phillips Idowu had to settle for fourth place in the triple jump, but the 31-year-old was fairly satisfied with a season's best of 17.25m, just seven centimetres behind winner Christian Olsson, the former Olympic champion making a comeback after several years of injury problems.
"I'm not too concerned," said Idowu, who will defend his world indoor title in Doha next month. "Christian is another competitor to beat and I went into Valencia showing similar form two years ago."
Scotland's Nick Smith gave the British selectors something to think about ahead of Monday's team announcement for Doha as he set a new national record of 6.60secs in the 60m, finishing third behind Michael Rodgers and Daniel Bailey but ahead of Mark Lewis-Francis in fourth and Harry Aikines-Aryeetey in fifth.
"I was happy to make the final but to run a PB and a Scottish record I can't really believe it," said Smith, who broke the record of 6.62 set by Elliot Bunney back in 1987.
"I don't know what the selectors will do now. I expect they'll take Harry because he was second at the trials and has the qualifying but I hope I've given them something to think about."
Olympic finalist Tom Parsons achieved the qualifying height for Doha in the high jump, clearing 2.28m with his first attempt.
The local favourite, born in Solihull, finished third on countback to British team-mate Samson Oni, with world champion Yaroslav Rybakov of Russia winning with a clearance of 2.31m.
Parsons said: "It's nice to finally get the qualifying height, I'd entered an open meeting tomorrow just in case but thankfully I don't need to jump now."
Kate Dennison set yet another British record in the pole vault, improving her own mark for the third time this year by clearing 4.60m, an improvement of three centimetres. Brazil's Fabiana Murer won with a national record of 4.82m.
Olympic champion and world record holder Dayron Robles stamped his authority on the field with victory in 7.44secs and Ireland's David Gillick, the former European indoor champion, equalled his personal best and national record with a time of 45.52secs in winning the 400m in impressive fashion.
Gillick said: "It's my first race of the year and it was tough but it's a fast track and it's not often we get to run in such a stadium in front of such a crowd. I won the European Indoors here in exactly the same time so it's a pity I couldn't dip and break my record."
In the 800m Andrew Osagie and Ed Aston both achieved Doha qualifying standards with personal bests of 1:47.71 and 1:48.24 respectively after finishing third and fifth behind winner Marcin Lewandowski of Poland.
"I'm really chuffed to get the time, training has been going well and it's all paying off now," Osagie said.
