Instead of watching the 6 Nations championship this weekend, he will be in Canada preparing to set off for his ultimate challenge - The Yukon Arctic Ultra. The journey is the world's toughest endurance race and involves Lewis and his team trekking 300 miles through the Arctic over 8 days. This video shows Lewis going through his final training session, and we also see him help rescue a driver from the recent UK snowstorms.
