Meadows continues her fine form after impressing in Berlin last year
Jenny Meadows secured her World Indoor Championships 800m place on Sunday and admitted she would be disappointed not to win a medal in Doha next month.
Meadows led from start to finish in Sheffield at the World Trials and UK Championships for a new stadium record and her sixth national title.
"I'm hoping I can produce a good performance in Doha," she said.
"It's still a big ask, it's a global event, but I'd be gutted if I didn't win a medal."
The World Indoors in Qatar are on 12-14 March.
Meadows, last year's World Championships bronze medallist, finished in two minutes 00.91 seconds - more than two seconds ahead of Liverpool's Vicky Griffiths, who also achieved the qualifying standard.
"I would have like to have run 1:59 but 2:00 on my own is quite good four weeks before Doha," added Meadows.
"I had no idea if I had a big gap or not so half of me was hanging back a little bit to make sure I had enough for the last 150m. I wish I would have pushed on a little bit more maybe but it's great how I felt at the end of that race.
"I wasn't really out of breath at all which was great to show I have a lot more in me. After Birmingham next weekend I'll have faced all my opponents in Doha and after that I will have three weeks to get it right.
"I'm one of the most experienced indoor runners but I've never particularly done myself justice so I want to walk off the track in Doha thinking I've done my best."
Helen Clitheroe, who has joined Meadows' training group this season, dominated her 1500m race to win in 4:13.90 and secure her place in Doha.
Kim Wall also achieved the qualifying standard in winning the 400m in 53.07 and 36-year-old Joice Maduaka clinched a sprint double winning the 200m in a season's best of 23.48 after Saturday's victory in the 60m.
The men's 1500m final was a tactical affair won by Colin McCourt in 4:04.83, eight seconds slower than the previous slowest in championship history and more than 22 seconds outside the qualifying time.
The weekend's action began with an impressive showing by Dwain Chambers on Saturday, with the 31-year-old winning the 60m for the third successive year in 6.50, the fastest time in the world this year.
Although 2012 remains the big target for many of Britain's athletes, this year sees the European Championships in Barcelona in July, while the Commonwealth Games take place in India in October.
