13 is a lucky number for dogs if they are pulling a Mackey in their sled. First Rick, then Dick and now Lance have won the legendary Iditarod, the Alaskan marathon for huskies. The family winners all took bib number 13 and won the event on their sixth race. As far as dog races go (and this one is 1,770km) the Iditarod takes the dog biscuit, lasting anything from nine to fifteen days. This year's sled contest took Lance Mackey nine days, five hours and eight minutes. And not content with simply one win this year, he's also the first musher to win both the Iditarod and the Yukon Quest in the same year.
