BBC Sport - Sir Bradley Wiggins targets fifth Olympic gold in Rio

Fifth gold medal big goal - Wiggins

British cyclist Sir Bradley Wiggins says winning a fifth gold medal at the Rio Olympics in 2016 is a "big goal".

The 2012 Tour de France champion admits it will be a "tough call" for Sky Pro Cycling's management to select a team to support defending champion Chris Froome at this year's Tour de France.

Wiggins also reflects on his hopes to work in the "grassroots" of cycling after his retirement.
