Nicola Adams: boxing, flyweight
Won the second of two world silvers just after returning from a year out with a crippling back injury. Injury-free she should win.

Paul Goodison: sailing, laser
Will be overwhelming favourite to defend his Olympic title in Weymouth and continue Britain's boating brilliance.
Alistair Brownlee: triathlon
The Yorkshireman has been a prolific winner since finishing 12th as a 20-year-old in Beijing.
