Both Renault drivers pitted immediately, but Räikkönen was unable to do the same, having just passed the pit entrance. Though this seemingly put Räikkönen in a bad spot, as all of his close competitors had pitted, he fought back with a series of brilliant laps that would give him a 34.7-second lead by the time he pitted on lap 42. Alonso, whose car was substantially slower as it was full of fuel, and whose rear tyres were wearing rapidly, was unable to catch up, and Räikkönen, after pitting, returned to the track still 13 seconds ahead. He would go on to win the race having led every lap of it.
Nick Heidfeld worked his way up from sixth grid position, passing his own teammate in the pits after Williams called him in a lap earlier whilst Alonso was badly holding the two Williams drivers up. After Heidfeld's stop, a superb overtaking manoeuvre into the Nouvelle chicane put him ahead of Alonso. Webber tried to follow suit a lap later, but on the first attempt Alonso missed the corner yet stayed in front, and on the second attempt succeeded for good. Alonso straggled into fourth, his rear tyres almost entirely bald. Montoya advanced from sixteenth on the grid to an eventual fifth, finishing on Alonso's tail, followed by Michael and Ralf Schumacher, who crossed the line almost side-by-side.
