Preet Chandi, does a solo trek across Antartica, skiing 700 miles for 40 days, doing about 17 miles a day. She had a 90 kilogram sled she pulled across sastrugi ridges in the hard snow and ice. Chandi says "I want people to push their boundaries and believe in themselves. No matter where your start line is, everybody starts somewhere." She trained on the icecap in Greenland and in ultramarathons in the Sahara to be able to do this. Preet Chandi is the first Asian woman- only a Swedish woman and another British woman have achieved this. Preet Chandi is a British army physiotherapist from Derby, England.
