Cain's Quest is one of the world's longest endurance snowmobile races that occurs every 2 years in Labrador. A team of two racers make a 3100 km trek around perimeter of the province over several days. Teams from all over the world come to compete in this race that pushes their bodies and machines to their limits. The race runs day and night as racers use GPS and instinct to get from checkpoint to checkpoint to hopefully win the race and the prize!
