The aim to raise cash to battle Africa's biggest killer- malaria, which kills a child in every 30 seconds across the continent.

Greg said: “We've working on strength and core stability and making sure thay are all used to walking long distances.

"Climbing Kilimanjaro is the equivelant of doing a marathon uphill so the demands are quite extreme.

“In addtion we've been working on the effect walking at altitude can have on body and the recognition of the altitude sickness.

"To do this we've used an acclimatisation chamber in Bisham so so that everyone could experience first hand what it is like walking at altitude.”

The group of celebrities and Greg will depart on February 27.
