Prince Harry and his 12 teammates officially reached the starting point of their 208-mile walk across the South Pole Wednesday.

They are a week behind schedule after a blizzard snowed them in at a base camp in Novo.

On Monday the royal joked with News Sky that his older brother, Prince William, is probably jealous of his journey and their father is a worried.

"I think [William] is just quite jealous that I managed to get away from a screaming child...[But] my father was a little bit concerned. I tried to keep him calm saying the North Pole was the dangerous one because we're walking on a frozen ocean. Whereas this time [we're going] around that."
