His jockey Tom Queally then set him alight far too early at Royal Ascot where he was lucky to hang on for a narrow victory.
The trick for Queally tomorrow will be to harness Frankel's energy through the race before asking him to stretch away perhaps two furlongs from home.
Ridden correctly, Frankel has the ability to take out three, maybe four lengths from any horse in training in the twinkle of an eye. But with only four runners he may well be much keener than his jockey would wish in the early stages.
If Queally gets his timing wrong, he knows that Hughes will be in his slipstream on Canford Cliffs, waiting to mug him on the final run to the line.
Hughes concedes: "I think Frankel is brilliant and my fellow will need to be at the top of his game to beat him. But if they go slow Frankel will not settle, especially when they turn downhill. And if there is no pace then maybe I'll have to make my move at the same time as Tom."
The pressure is unquestionably on Queally as the moment of truth beckons though he plays down its significance.
"It is only horses racing each other," he says. "Everyone is different and I've always been laid back. I care but you can't let it get to you. I will not be having any sleepless nights about it."
Freddy Head arrives from France tomorrow hoping to spoil the party with his much improved colt Rajsaman, beaten narrowly by the mighty Goldikova last time.
"It will be a very tough race," he admits. "We are not going there thinking we will win but you never know. If you don't run you cannot win".
