Nigel Mansell will fly back from practice for the Le Mans 24 Hours to launch an extreme cycling challenge, which he will undertake in July and August this year.

The 1992 F1 world champion has been given special dispensation by the Le Mans stewards to attend the opening of Motorexpo on 7 June, when he will reveal details of the ride, which will see him joined by sons Leo and Greg - as well as former professional cycle racer and 2004 Paris-Roubaix race winner Magnus Backstedt - on a 1200-mile trip around Britain in just 13 days, from 22 July to 3 August.

Mansell, now president of the charity UK Youth, will also attend major events organised around the country, by the UK Youth Bike Clubs, Youth Achievement Foundations and youth centres. The start of the Cycle Challenge will be at Kensington Palace, overseen by HRH Prince Michael of Kent, one of the patrons of UK Youth.

To put the effort into perspective, the Tour de France covers 2200 miles in 21 days - but with a two-day rest in the middle - but Mansell has set himself the challenge of raising public awareness of both the work of UK Youth and the launch of its 'Positive About Youth' campaign. It is a challenge that will be undertaken with familiar determination, despite doctors advising him not to take part after suffering a back broken three times, numerous breaks to his hands, feet and legs.

The 'Positive About Youth' campaign has been undertaken to change the negative public perception of young people and highlight the numerous amazing feats which young people achieve every year. The key stopping points along the route will be Cardiff, Chester, Worcester, Manchester, Blackpool, Carlisle, Glasgow, Edinburgh, Hexham, Harrogate, Lincoln, Leicester, Silverstone and Leighton Buzzard. Mansell, meanwhile, will take time during the launch to answer questions about his racing career, preparing for Le Mans and why he is taking up the challenge to get us all to be more 'Positive about Youth'.
