When the money starts to go down big time before a major race, then you know that it's not without good cause.
We saw it only a few weeks ago with Aidan O'Brien's So You Think, who was backed off the boards to beat Workforce in Sandown's Eclipse Stakes. The O'Brien horse obliged in fine style, landing quite a punt in the process.
The latest betting momentum is behind Workforce to steal the limelight from O'Brien's St Nicholas Abbey in the 60th running of the Betfair King George VI and Queen Elizabeth at Ascot on Saturday.
Recently, trainer Sir Michael Stoute could not get a winner in a one-horse race, but the picture has changed in the last couple of weeks and all reports are that Workforce is in tip-top condiditon and will get the juice in the ground which seems to favour him.
At 2-1, that price has to be taken as last year's Derby and Arc winner — 20-1 on the exchanges a few weeks ago because of doubts about him running — will be even shorter come Saturday.
Of course, the memory of Workforce's poor performance in last year's King George has to be forgotten but the weight of monetary support suggests it has been.
Workforce and Rewilding, who got the better of So You Think at the Royal meeting over a mile and a quarter, stand out on Timeform ratings but the recent rain is expected to favour Workforce as his best performance in the Arc came on soft ground.
