The Sahara is the world's largest desert, stretching all the way across Africa from Senegal in the west to Egypt in the east. The 5,900-kilometer expanse is largely uninhabited, and in the harsh environment there are few water sources. Until this year there was no record of it being crossed successfully from end to end by a human being on foot.
撒哈拉是地表最廣大的沙漠，西起塞內加爾，東邊深入埃及，橫亙非洲，直線距離約 5,900 公里，多數為無人之境，狂沙酷熱且缺乏水源，尚無人類成功橫越的紀錄。
