On his JustGiving page Philip Goodeve-Docker wrote of the dangers he would face travelling across one of the most "deadly landscapes in the world". He said the challenge across the world's second largest ice cap from east to west would take 30 to 35 days.
"We will travel 550-600km across one of the most dazzling, beautiful, yet barren and deadly landscapes in the world, dragging all our own supplies (between 100-135kg) on individual pulks (sleds)," he said.
"This is one of the great polar challenges, through which we face such dangers as polar bears (not cute and cuddly), crevasses up to 500+ metres deep, polar winds, temperatures of 5C to -50C, plus the horror of 3 men with one tent & no washing."
