London, October 18 : Prince William and Prince Harry were spotted in a relaxed mood before starting of the charitable 1500 mile motorbike trek across Africa.
The royals were in a jovial mood as they posed for pictures in red biking gear covered by matching white t-shirts at the start of the Enduro Africa charity ride.
The rally that begins on Port Edward on October 18 will see the two princes compete in the gruelling week-long trek to raise money for UNICEF, the Nelson Mandela Children's Fund.
Donation for 'Sentebale', a charity that supports orphans and vulnerable children in Lesotho and was founded by Prince Harry , shall also feature in their list of fundraising act.
With 80 riders and motorbike owners participating, the event has managed to raise more than 300,000 pounds for charities.
A spokesman for Global Enduro, the adventure company which runs the Enduro Africa event, said both accomplished riders and motorbike owners had graced the event with their presence.
"We're looking forward to riding with them and, as they are both in the Armed Forces, I'm sure they will have the grit to get through because it's not easy," the Telegraph quoted the rep, as saying.
"There are no road signs and it's not like riding anywhere in the UK so they will need a guide.
"They will go through game reserves, tribal areas and wild areas," the rep added.
A Clarence House spokesman further said: "The Princes are looking forward to the motorcycle ride that will raise money and the profile of Sentebale, a charity very close to their hearts, and two other major charities in southern Africa."
