Bookmakers have revealed a late flurry of bets on Jessica Ennis being crowned BBC Sports Personality of the Year.
Odds on the Olympic heptathlon champion taking the award have fallen from 9/1 to 4/1 in the last 48 hours, betting company William Hill said.
She is now firmly second favourite behind cyclist Bradley Wiggins, who is odds-on to win after his historic triumph in the Tour de France and gold in the Olympics time trial.
William Hill spokesman Rupert Adams said: "There is no doubt that momentum has swung away from Bradley and Jess is steaming up on the outside. The only question is has she left her run too late?"
