It's like weird Extreme Sports
8. Iditarod Trail Invitational
Racing from Anchorage, Alaska to Nome on the western Bering Sea coast. A trajectory so grueling that competitors have to practise for at least 10 months before it starts. Jagged mountain ranges, dense forests, desolate tundra, and treacherous climbs in blinding winds and bladder-freezing temperatures in endless hours of darkness are but a few of the hazards. The recent advent of GPS systems has eased the stress slightly - but even they’re not a failsafe. The current finishing record stands at eight days, 22 hours, 46 minutes and two seconds. The prize? There is none. Except that the first male and female across the line get free entry for the following year.
