Sir Bradley Wiggins has withdrawn from this weekend's 2015 British Track National Championships in Manchester after suffering from an illness in the wake of the Tour of Britain.
Wiggins is reportedly suffering from a cold after competing in the ToB with his eponymously-named squad, Team Wiggins.
The 2012 Tour de France winner's appearance at the British Track Champs - his first for 10 years - was planned to be part of his preparations for the 2016 Olympic Games in Rio, where he is aiming to take part in the team pursuit and add to his current collection of seven Olympic medals.
One more gold medal would see Wiggins equal rower Sir Steve Redgrave's tally of five Olympic titles in the all-time list of British Olympians. Track sprinter Sir Chris Hoy is top with six gold medals. However, should Wiggins secure another medal of any colour, he would top the table for the most number of medals overall (eight) as he also has a silver and two bronzes.
Watch: Secrets of the toolbox - Team Wiggins
Wiggins left Team Sky in April after competing in Paris-Roubaix, effectively drawing his illustrious road career to a close. He set a new Hour record of 54.526km in June, signalling a successful start to his switch back to the track.
The 35-year-old Londoner took part in the Revolution Track Series opener in Derby in August, partnering with Mark Cavendish in the Madison event.
Wiggins is expected to take part in the European Track Championships in Grenchen, Switzerland, over October 14-18.
The British National Track Championships take place at the National Cycling Centre, Manchester, over September 25-17.
