I was looking at the internet and found there is another long distance snowmobile race similiar to the Irondog called the Cain's Quest. The race is 2,300km (1,429mi) across some of the most desolate parts of Canada.
It sounds like a pretty grueling race.
There are several USA teams with some real good ones from Maine.
According to the Cain's Quest website only 50% of the racers who enter finnish the race.
This year Skidoo won again taking the top 2 spots with teams riding 800 Etec freerides. Last year they took the top 3 spots with Etec powered machines . A team riding Arctic cats took 3rd this year.
I guess last year they had to haul an extra 30 gallons of fuel to make the stops. The Etec powered Skidoos kind of had an unfair advantage with their extremly reliable and fuel efficient engines.
