There are challenges everywhere in the world like crossing deserts on foot, to climb mountains, to fly in a glider, to cross the river by swimming against the current, to travel from coast to another coast. All these challenges are hard to fulfill in a limited time but it is very interesting to venture out to do it. There is lot of preparations, skill and perseverance to accomplish it. I think this is the perfect challenges if ever there was won that will encourage interaction and gain knowledge of that particular area environment and the difficulties faced and there remedies. This could be a fun challenge for everyone whosoever venture out to do it.
