While this morning's GP3 race took place in mainly damp conditions - allowing Adrian Tambay, son of former F1 winner Patrick Tambay - to take a brave win - the subsequent GP2 sprint race was run in the dry.

Nonetheless, both races featured the traditional madness indeed, such was the mayhem during yesterday's GP3 race we are still awaiting the official result over twenty hours later - such were the number of penalties handed out.

Earlier this morning it was claimed that there was only a "small" chance of rain during today's race, but as we know from experience it is best to take these predictions - especially in the micro climate that is the Ardennes - with a large pinch of salt.

What with penalties handed out after yesterday's qualifying session - not to mention Michael Schumacher's ten-place hit for his silliness in Hungary - the grid has been substantially revised. So much so that Kovalainen is starting from thirteenth and Bruno Senna eighteenth.

It was noticeable during the GP2 and GP3 events that drivers are following Kimi Raikkonen's 2009 example and using the wide run off at the exit to La Source to great advantage however, the F1 drivers have been warned that if they follow suit they will be punished.

Mark Webber has said that the race will not be won on the first lap, which is probably true. However, it could most certainly be lost. Therefore, whatever the conditions, drivers would be advised to take due care at the notorious first corner and again at Les Combes - where Hamilton and Button came a cropper last year.

Despite showing promise during the early part of the weekend, Fernando Alonso starts from tenth today having got his tyre strategy wrong in Q3. Consequently, the Spaniard has it all to do today, though his Brazilian teammate starts from sixth.

Providing it remains dry, Webber has to be favourite here, though Hamilton is sure to give the Australian a hard time.

Red Bull has made much of the fact that Spa and Monza won't suit the RB6 but we're sure that there are quite a few drivers out there today who would happily swap seats - including Messrs Schumacher and Rosberg.

However, the real dark horse here today has to be Robert Kubica in the seriously upgraded Renault, the French team having introduced its version of the F-duct to great effect. After a hugely disappointing outing in Hungary the Pole will be keen to make amends

While we expect today to be all about the Red Bulls, McLarens and Kubica, it will be worth watching the two Williams - particularly Rubens Barrichello who would love to celebrate his three-hundredth race with a strong result - and the Force India of Adrian Sutil, the Indian team having come so close to pulling off a sensation here twelve months ago.

As the drivers make their way to the grid, performing final systems checks before the pitlane is closed, it is bright, even the occasional bit of sunshine, but cool. Some teams are now predicting that there will be a downpour around one hour into the race. This could mean problems for those drivers - including Vettel - who are seriously low on intermediates.
