* Lap 1: After qualifying on pole position for the third consecutive race – and the sixth time in his Formula One career – Kimi Räikkönen repels fellow front-row qualifier Fernando Alonso into Ste Dévote and pulls away by 1.2 seconds during the lap. Mark Webber makes a slow start and loses places to both Giancarlo Fisichella and Jarno Trulli. Nick Heidfeld settles into sixth ahead of David Coulthard, Michael Schumacher, Felipe Massa (up from 11th on the grid), Jacques Villeneuve, Rubens Barrichello, the penalised Juan Pablo Montoya (who started 16th after having his qualifying times deleted for causing an avoidable accident in Saturday morning’s free practice), Vitantonio Liuzzi, Patrick Friesacher Christijan Albers Tiago Monteiro, Ralf Schumacher and Narain Karthikeyan.
* Lap 2: Räikkönen increases his advantage to 1.7s. The top three begin to edge away from Trulli.
* Lap 3: Ralf S passes Monteiro for 16th.
* Lap 4: Ralf S moves up another place, at Albers’s expense.
* Lap 5: Räikkönen cuts his fastest lap to 1m 17.032s and leads by 2.3s. Alonso is 1.4s clear of Fisichella.
* Lap 6: Alonso is into the 1m 16s – 1m 16.835s.
* Lap 8: Ralf S passes Friesacher for 13th.
* Lap 9: Räikkönen laps in 1m 16.502s.
* Lap 10: Räikkönen leads by 2.2s. Alonso is 1.7s clear of Fisichella. Ralf S apart, the order has not changed since the start – although Webber is putting Trulli under fierce pressure. After a particularly slow lap, Karthikeyan pits.
* Lap 11: Karthikeyan comes in again but rejoins.
* Lap 13: Another fastest lap for Räikkönen: 1m 16.495s.
* Lap 18: Räikkönen laps in 1m 16.414s. Trulli and his suitors lose about four seconds while lapping Karthikeyan.
* Lap 20: Räikkönen laps in 1m 16.235s, leads by 5.4s. Two laps in arrears, Karthikeyan pits again.
* Lap 21: Karthikeyan makes his fourth stop – and this time goes straight into his garage.
* Lap 24: Albers spins at Mirabeau while being lapped. Coulthard swerves round him but is clipped by Michael S and the following cars all come to a halt. The Safety Car is deployed while the mess is cleared. Massa makes a smart pit stop at the end of the lap. Coulthard comes in, too, but retires. Michael S pits for a fresh nose.
* Lap 25: Räikkönen eschews the pit entrance but Alonso, Fisichella, Webber, Heidfeld and Friesacher all come in. Fisichella and Heidfeld lose time queuing behind their team mates.
* Lap 29: Race restarts with Räikkönen leading Trulli, Alonso, Webber, Heidfeld, Massa, Villeneuve, Fisichella, Barrichello, Montoya, Liuzzi, Ralf S, Michael S, Friesacher, Monteiro and Albers. Räikkönen pulls 5.6s clear of Trulli, who is behind the lapped Michael S.
* Lap 31: Friesacher crashes exiting the tunnel and climbs unaided from his crumpled Minardi.
* Lap 33: Räikkönen is 13.8s ahead of Trulli – and 17.0s clear of Alonso.
* Lap 34: That’ll be a 1m 16.222s for the leader, then. He is dropping Trulli by more than a second per lap. The heavily-fuelled Alonso is going more slowly than both.
* Lap 36: Still running between the two leaders, 13th-placed Michael S is lapping more quickly than anyone bar Räikkönen
* Lap 37: Villeneuve pits and slips from seventh to 12th. Monteiro refuels, too.
* Lap 39: Trulli pits and rejoins 11th. Michael S sets a new fastest lap – 1m 15.995s. Albers pits (although his rivals are on lap 42 by now).
* Lap 40: Michael S laps in 1m 15.842s.
* Lap 41: Ralf S pits.
* Lap 42: Leading by 34.7s, Räikkönen pits and rejoins more than 13s clear of Alonso. Webber is third from Heidfeld, Massa, Fisichella, Barrichello, Montoya, Liuzzi, Trulli, Villeneuve, Ralf S, Michael S and the distant Monteiro and Albers.
* Lap 45: Liuzzi and Barrichello pit. The Brazilian stalls – and then lands a drive-through penalty for speeding.
* Lap 46: Montoya is the last driver to refuel.
* Lap 47: Post stops, Räikkönen is 15s clear of Alonso – who has the Williams-BMWs queued up behind him. Webber lies third from Heidfeld, Massa, Fisichella, Trulli, Montoya, Villeneuve, Ralf and Michael S (now back on the lead lap), Liuzzi and Barrichello.
* Lap 48: Barrichello serves his penalty but remains 13th.
* Lap 50: Massa pits and slips from fifth to seventh.
* Lap 54: Alonso has eased his pace by four seconds and is under huge pressure from Webber.
* Lap 55: Michael S tries to pass his brother at the chicane, but fails and goes sailing over the kerbs.
* Lap 56: Barrichello passes Liuzzi.
* Lap 57: Heidfeld refuels.
* Lap 58: Webber follows suit – and rejoins behind his team-mate. Michael S comes in and slips to 13th, on Liuzzi’s tail.
* Lap 60: Liuzzi pits with a punctured right rear and retires. Fisichella, in fifth, heads a queue of cars stretching back to 12th-placed Barrichello. Räikkönen is on his own at the front, half a minute clear of Alonso.
* Lap 63: Villeneuve tries to pass Massa at Ste Devote, but he hits the tyre wall and forces his team-mate down the escape road.
* Lap 64: Trulli passes Fisichella at the hairpin and most of the queue follows him through. Trulli then runs over the chicane kerbs and loses several places himself.
* Lap 65: Trulli pits. Räikkönen leads Alonso, Heidfeld (half a second adrift of the Spaniard), Webber, Montoya, Ralf S, Barrichello, Michael S, Fisichella, Massa, Trulli and Villeneuve as the midfield calms down (a bit, although Montoya and Michael S, three places apart, are separated by a couple of seconds).
* Lap 71: Heidfeld pounces at the chicane and passes Alonso for second as they come up behind the lapped Trulli.
* Lap 73: Webber tries to emulate Heidfeld at the chicane, but both cars runs wide and Alonso stays ahead after bobbling over the kerbs.
* Lap 74: Webber and Alonso stage a near-carbon copy… but this time the Australian makes it stick. He has lost almost 10s to Heidfeld in the intervening three laps. Montoya is now within 5s of Alonso – and closing fast.
* Lap 77: Alonso has Montoya, Ralf S, Barrichello and Michael S on his tail. Barrichello all but clips Ralf S at Mirabeau.
* Lap 78: Räikkönen wins by 13.8s from Heidfeld and Webber – both of whom record career-best finishes. Alonso holds on to fourth by 0.1s from Montoya. Michael S passes Barrichello at the chicane and crosses the line seventh, less than a tenth behind his brother. Massa, Trulli, Villeneuve, Fisichella, Monteiro and Albers complete the classified finishers.
