Dame Kelly Holmes began her last outdoor season with victory in the 1500m at the Norwich Union International in Glasgow. The double Olympic champion moved ahead in the home straight to hold off Russian Yelena Zadorozhnaya with Britain's Helen Clitheroe in third.
"I was nervous about this as it was the first race of the season but the home crowd lift you," Holmes told BBC Sport.
"It's quite sad because I know I am never going to race here again."
Mark Lewis-Francis edged out former world record-holder Maurice Greene by 0.1 seconds to win the 100m.
In windy conditions that were far from ideal, Lewis-Francis was quickest out of the blocks and clocked 10.43secs to nudge out the American.
Lewis-Francis' fellow Olympic relay gold medallist Jason Gardener was third in 10.50secs.
"I'm focused and I'm on the right track," Lewis-Francis told BBC Sport.
It was the 22-year-old's first UK competition since he was stripped of his European Indoors silver and given a warning after testing positive for cannabis.

"I'm putting that behind me," said Lewis-Francis.
The competition, which marks the start of the outdoor season, pitted Great Britain against Russia and the USA.
Russia eventually won with 118 points from the USA with 108 points while Great Britain finished with 92 points.
Lewis-Francis later led the GB men's 4 x 100m relay team to victory over the USA team, just as he did at the Athens Olympics last summer.
Two of the other three relay gold medallists - Gardener and Marlon Devonish also ran with Chris Lambert replacing Darren Campbell.
The GB quartet ran 38.92secs to hold off a weakened American team, which did not include Greene.
Heptathlete Kelly Sotherton just missed equalling her personal best when she produced a best effort of 6.64m in the women's long jump.
It was an impressive mark considering the less-than-ideal conditions and saw her finish thrid behind Olympic silver medallist Irina Simagina, who won with a leap of a wind-assisted 6.68m.
Britain's Jo Pavey produced a positive front-running display to take the women's 3,000m in a time of 8:45.79.
British runner Malachi Davis won the men's 400m to score some valuable points against his one-time American team-mates.
California-born Davis, who received a British passport before last year's Olympics, stayed strong in the final stages to come home in a time of 46.48secs.
In the women's 100m, Britain's Joice Maduaka was third behind Russian Olga Fyodorova, who won in 11.63secs.
Maduaka, who heads the British rankings with a time of 11.46secs in Hengelo last week, clocked 11.75secs into a headwind.
World champion John Capel showed in class by easing to victory in the men's 200m.
The American finished easing up in a time of 21.04secs, well ahead of Britain's Christian Malcolm who was second in 21.13secs.
James McIlroy was second behind European Indoors champion Dmitriy Bogdanov in the men's 800m, who won in a time of one minute 47.68secs.
The Northern Ireland-born McIlroy, who was fourth in the European Indoors, led in the home straight but tied up in the last 100 yards to finish in 1:47.68.
In the men's long jump, world and Olympic champion Dwight Phillips set a new stadium record by leaping 8.26m to beat fellow American Miguel Pate.
British jumper Greg Rutherford came fifth with a new personal best of 7.63m.
