Pietro Simonetti Pietro Simonetti is not new to the idea of performing extreme stunts to raise money for a good cause. In March of 2002, Pietro and 4 other friends set a Guinness World Record by skiing all Colorado's 28 resorts in a time of 80 hours, 41 minutes for the National Sports Center for the Disabled. In 2001, Pietro found himself standing on top of Aconcagua, the highest mountain in the Western Hemisphere (23,000 ft.). Proving he cannot get enough of life at the top, Pietro also traveled to Makalu Base Camp in Nepal to undergo a series of tests to study the effects of high altitude on his own body. This research was sponsored by the University of Colorado at Boulder, and led to improvements to the high altitude Gamov bag. Pietro will be one of two skiers on the Kilimanjaro expedition who will make their descent down the Heim Glacier.
