Four days into his trip, about 100 kilometres short of Eagle Plains, his toes froze.

Its insidious, he says. It can sneak up on you because obviously once your extremities get to a certain temperature you can't feel them anymore, so there's no warning sign that youre freezing.

But my concern was my feet because you're not using your feet on a bike. Even though you're warm on a bike, your feet are basically sitting on the pedaldoing nothing. They're basically a point of contact on a bike.

St.Germain says he had to stop because if his big toe was frostbitten again on the trip, he would have lost the toe.

Its not the first time St. Germain has experienced frostbite.

He lost three fingers on a previous adventure.

St.Germain, 42, is a pilot for Canadian North, and his adventures have taken him all over the world.

In 2010, he was the first Canadian to reach the summit of Everest without the aid of oxygen. Last year he climbed the tallest mountain in Iraq with a pair of skis on his back.

St.Germain says, despite the difficulty, he'd like to try the Dempster ride again.
