Edward Norton has signed up to run the New York Marathon after training for the big race with Maasai tribesmen in Africa.
The actor, 39, will hit the streets with three of the guys he trained with on 1 November (09).
He'll be running to raise awareness and funds for the Maasai Wilderness Conservation Trust, which aims to protect the east African grasslands which the Maasai tribe calls home.
One of his co-runners is safari guide Parashi Ntanin, who is so fast he could complete the marathon course in less than 150 minutes.
Norton, who was a champion rower at Yale University, is confident he'll complete the race, even though he's struggling with leg and knee pain.
He says, "I'm enjoying having a goal."
