Rio 2016: Sir Bradley Wiggins says he may not retire after Rio Olympics

Sir Bradley Wiggins says he may continue to race on the track into 2017 having previously said he intended to retire after the Rio Olympics.

The 2012 Tour de France winner returned to the GB team pursuit squad two years ago with the aim of winning a last Olympic gold before ending his career.
"It's not 100% yet," Wiggins, 36, said.
"I have races I'm committed to until the end of the year and then I'll decide - it might be on a yearly basis after that."
And he told BBC Sport: "I'm enjoying it as much as ever now. My progression over the last 12 months in this discipline has been such a sharp rise."
Wiggins will take part in his fifth Olympic Games after being officially named among 26 Team GB cyclists to compete in Rio this summer.
In April 2015 he took part in his final road race at Paris-Roubaix before turning to concentrate on the team pursuit with the aim of track success in Brazil.
Wiggins began his career in track cycling and had said winning gold in Rio in the team pursuit would be "a nice way to end my career".

In February, he won World Championship silver in London and later indicated he would take part in further races until the end of the year, but now he could prolong his career into 2017 and beyond.
"At the moment I'm just focusing on these Olympics and I'm going to allow myself the time to keep that option open if I feel like continuing or not," he said.
In Rio, Wiggins could become Great Britain's most decorated Olympian of all time.
