Tom Fletcher, Danny Jones, Dougie Poynter and Harry Judd launched ASK Italian's Grand Tour yesterday (5 September), which aims to raise £250,000 for Great Ormond Street Hospital Children's Charity.
The fundraising initiative was set up by the Italian restaurant chain and will see celebrities and members of the ASK Italian workforce cycle, swim and run more than 2,500 miles in return for sponsorship.
Starting in Aberdeen, the tour will visit every ASK Italian restaurant in Great Britain to collect locally raised funds and it will finish at Great Ormond Street Hospital in London on 27 September.
The boys, along with other celebrities including retired footballer Lee Dixon, retired rugby player Lawrence Dallaglio and chef Theo Randall, will don swimming caps and trainers as they reveal their sporty sides to reach the high fundraising target.
Mcfly have said: "Great Ormond Street Hospital Children's Charity is a fantastic cause, we're happy to endorse the Grand Tour.
"It is a great initiative that we're sure will raise important funds for the charity as well as giving the public a chance to get involved too."
Hoping to be a fun and exciting way to raise money for charity, ASK Italian want the public get involved and have a go too.
Steve Holmes, ASK Italian MD, said: "We hope the Grand Tour will capture the spirit of ASK Italian, raise a huge sum of money for a charity close to our hearts, celebrate our passion for real Italian food and culture and of course, have some fun along the way."
