Canicross

The term canicross is of European origin.  Cross means to move cross country.  Canicross is cross country with your dog.  Canicross is the sport of running or walking your dog in harness with equipment similar or the same used for skijoring.  Canicross is not simply waling the dog.  Running with a dog on a leash is not canicross.  In canicross the dog pulls you, just like skijoring.  Your hands are free because your dog is attached at the belt.  You need a belt a line with an integrated shock cord and a harness for the dog.  Using ski poles when canicrossing will keep your poling muscles in shape in the off season.  You can double pole or stride with poles, mimicking skate skiing and classic.
