Sharma, who works with the Navy on the civilian side, funded his own trip, waiting fruitlessly for his sponsors to release funds.
Sharma, who hails from Rajasthan, and now lives in Mumbai, is a mountaineer. He has climbed several peaks around 17,000 to 22,000 feet. A friend from the Navy introduced him to running and he ran a 42-km marathon in his first attempt! Over the course of many runs he realised that he was made for longer and sterner stuff and started running longer distances. To prepare for the Badwater marathon, he ran a series of 100 milers that set him up for the journey. Sharma feels his Rajasthani roots helped him overcome the heat problem.
