Three Canadian trekkers broke world record for the fastest trip across Antarctica to the South Pole.

Ray Zahab, Kevin Valley and Richard Weber reached South Pole Wednesday after walking unaided through 1,300 kilometers on skis, snowshoes and foot in 33 days, 23 hours and 30 minutes.

They started from Hercules Inlet on the Ronne Ice Shelf. They broke the record set last month by American adventurer Todd Carmichael who made the same journey in 39 days and 7 hours. The previous record holder prior to Carmichael was Briton Hannah McKeand who traveled the same distance in 2006 in 39 days and 9 hours.

Despite covering their body and faces, Weber and Zahad had sunburns from light reflected off the snow. Their daily diet includes Gatorade and other high-fat food such as butter and pemmican meat mixture totaling 7,000 calories. They communicated home using a sun-powered satellite home.

Zahab, 39, is from Chelsea. Valley, 44, comes from North Vancouver, British Columbia and Weber, 49, hails from Alcove, Quebec.
