Sir Bradley Wiggins’ final race on British soil ended in disappointment as he and Mark Cavendish were edged out in the Six Day London madison.
The British pair, twice world champions in the event, were overtaken in the standings by Belgians Moreno de Pauw and Kenny de Ketele on the final day.
It was revealed in September that Wiggins took a banned steroid before his historic 2012 Tour de France win.
The 36-year-old had a therapeutic use exemption to allow him to use the drug.
While no rules were broken, some of Wiggins former team-mates and a doctor who worked with him at Team Sky say questions remain over his use of triamcinolone to treat allergies and respiratory issues.
Wiggins told the BBC’s Andrew Marr Show that his treatment put him “back on a level playing field” and that he didn’t gain any “unfair advantage”.
The 2012 Tour de France winner will retire after the Six Day event in Ghent – the city of his birth – in November.
The five-time Olympic champion said the Lee Valley velodrome, which hosted the London 2012 track events and was built on the site of the Eastway facility that he used as a boy, was an appropriate place to end his career in Britain.
“It has such fantastic memories for me. I will always come back – I’ll probably be back next year, but in the stands,” he told Eurosport.
De Pauw and De Ketele had led the competition before Cavendish and Wiggins leapfrogged them in the standings on Saturday evening, but gained a lap late in Sunday’s finale and took the final sprint to win by 11 points.
“It just shows what a class act they are – hats off to them,” said Wiggins.
