Bridgestone has teamed up with its four Formula One teams this week to 'Go the Extra Mile' for Sport Relief and to mark the occasion, they sported a single limited edition red Bridgestone Potenza Formula One tyre during this morning's pit stop practices ahead of the British Grand Prix.

The four Bridgestone equipped teams: Scuderia Ferrari, Sauber Petronas, Jordan Ford and Wilux Minardi Cosworth; have each given their support to the Sport Relief campaign, the biennial fundraising event set up by Comic Relief to use the power and passion of sport to tackle poverty and disadvantage, both in the UK and in some of the world's poorest countries.

Between them, the teams are donating numerous items of signed F1 team memorabilia which will be auctioned in aid of Sport Relief.

Earlier this week, Jordan Ford and Bridgestone teamed up to give the winners of the Sport Relief Pit Stop Challenge Competition a day they won't forget.

Proceeds from entering the competition to win a day with the Jordan Ford team at their factory and to take part in a Pit Stop Challenge are going towards Sport Relief. The winners also got the chance to meet Jordan Ford's drivers Nick Heidfeld, Giorgio Pantano and Timo Glock when they too decided to try their hand at changing the Limited Edition red Bridgestone Potenza Formula One tyre.

The significance of the Limited Edition red Bridgestone Potenza Formula One tyre is to mark the theme of this year's Sport Relief campaign which will see thousands of people up and down the country today running a mile wearing a single red sock. Coinciding with the anniversary of the 'Four Minute Mile' run by Roger Bannister in 1954, fourteen venues up and down the country are hosting a Sport Relief Mile with well-known faces from the world of sport and entertainment lining up alongside the public as the whole nation comes together to 'Go the Extra Mile'.

The Limited Edition red Bridgestone Potenza Formula One tyres, which were made especially for this weekend's Sport Relief activities by Bridgestone's technical centre in Tokyo, Japan, will be in action on the Bridgestone equipped cars this morning at the times listed below.

Details of how F1 fans can bid for items in the Sport Relief auction will be posted on the Sport Relief website - - in the coming days.
