* Pre-race: Expected all weekend, a rain shower finally materialises 45 minutes before the start. It passes quickly, although there is still moisture in the air as the countdown to the race continues.

* Lap 1: Pole position qualifier Kimi Räikkönen makes a flying start. From third on the grid, world championship leader Fernando Alonso grabs second from front-row starter Jenson Button – and Michael Schumacher muscles past the Englishman, too. Nick Heidfeld vaults from seventh to fifth to lead David Coulthard (up from 11th), Felipe Massa (up from 13th), Giancarlo Fisichella, Christian Klien, Ralf Schumacher, Juan Pablo Montoya (who started last after yesterday’s qualifying accident), Christijan Albers, Rubens Barrichello, newcomer Robert Doornbos, Jacques Villeneuve (who loses time after a biff from Barrichello), Narain Karthikeyan and Tiago Monteiro. Takuma Sato and Jarno Trulli pit for repairs after first-lap contact. Mark Webber pits and stays there for about 15 minutes. Räikkönen ends the lap 1.5s to the good.

* Lap 2: Räikkönen extends his advantage to 1.7s. Montoya passes Ralf Schumacher. Barrichello moves ahead of Albers.

* Lap 3: Montoya passes Klien for ninth.

* Lap 4: Villeneuve tries to pass Doornbos at Turn 8 but punts the Dutchman. Both drivers spin before pitting at the end of the lap and rejoining at the tail of the field. Doornbos replaces a damaged rear tyre.

* Lap 7: Räikkönen laps in 1m15.639s and leads by 4.1s.

* Lap 9: Alonso cuts his deficit to 3.7s.

* Lap 11: Räikkönen laps in 1m15.639s and starts to edge away from Alonso again. The rest are nowhere.

* Lap 14: Räikkönen leads by 6.3s. Monteiro makes the race’s first scheduled stop.

* Lap 15: Heidfeld comes in for fuel.

* Lap 16: Karthikeyan pits.

* Lap 19: Räikkönen laps in 1m14.995s and leads by 9.6s. Massa, Klien and Albers refuel.

* Lap 20: Button and Coulthard peel in.

* Lap 21: Doornbos serves a stop-go penalty for having refuelled at the same time as replacing a tyre damaged earlier by Villeneuve.

* Lap 22: Alonso and Michael Schumacher stop.

* Lap 23: Fisichella refuels.

* Lap 24: The leader posts a 1m14.373s.

* Lap 25: Räikkönen and Ralf Schumacher come in. The Finn rejoins 11.0s clear of Alonso.

* Lap 26: Barrichello and Trulli pit.

* Lap 27: Montoya is the final front-runner to stop. Villeneuve and Monteiro join him in the pits, however, after colliding on the approach to Turn 8. Both resume following remedial work. Stewards announce that a post-race enquiry will be held.

* Lap 28: Sato refuels.

* Lap 29: With the first round of stops over, Räikkönen leads Alonso, Michael Schumacher, Button, Montoya, Fisichella, Coulthard, Ralf Schumacher, Heidfeld, Massa, Barrichello and Klien. Trulli, Sato, Karthikeyan, Albers, Monteiro, Villeneuve and Doornbos are all at least a lap in arrears.

* Lap 35: Heidfeld makes his second stop.

* Lap 36: Räikkönen slows and stops on the track. Alonso takes command, 25.7s clear of Michael Schumacher.

* Lap 39: Klien passes Barrichello for ninth.

* Lap 41: Alonso remains well clear. Michael Schumacher is being made to work hard by Button – and Montoya, too, is close to the battle for second.

* Lap 45: Button passes Michael Schumacher at the hairpin…

* Lap 46: …but only stays ahead briefly because he pulls in to refuel. Massa and Klien do likewise.

* Lap 47: Alonso, Coulthard and Trulli pit.

* Lap 49: Both Ferraris pit. Michael Schumacher rejoins behind Button.

* Lap 50: Fisichella and Ralf Schumacher refuel.

* Lap 51: Having dropped behind Barrichello during the fuel stops, Klien passes him for the second time during the afternoon.

* Lap 53: Montoya loses time behind the duelling Heidfeld and Trulli, a lap down. Trulli gets a drive-through penalty for failing to heed blue flags.

* Lap 56: Montoya makes the final significant scheduled stop of the race. He rejoins half a minute behind Alonso – but comfortably clear of Button. Michael Schumacher is fourth, but facing fierce pressure from Fisichella – who has Ralf Schumacher not far behind. Coulthard is seventh, ahead of Massa and Klien. Barrichello is a lapped 10th, with Heidfeld, Sato, Trulli, Albers, Villeneuve, Karthikeyan, Monteiro, Doornbos and the unclassified Webber all still running.

* Lap 63: Fisichella has a look down Michael Schumacher’s inside but is sharply rebuffed.

* Lap 65: Fisichella gets even closer to Michael Schumacher. Again, no joy. Coulthard is now on the end of this chain, too.

* Lap 66: Fisichella passes Michael Schumacher at the hairpin.

* Lap 67: Alonso wins by 22.5s – his sixth success of the year – from Montoya, Button, Fisichella, Michael Schumacher, Ralf Schumacher, Coulthard, Massa and Klien. Barrichello, Heidfeld, Sato and Albers are next, from Trulli – who stops right at the end – Villeneuve, Karthikeyan, Monteiro and Doornbos.
