I have seen these dogs advertised locally.
I know of a few people that have had them, and are experiencing major health problems with them.
They are a crossbreed, which means that they cannot be raced with any British organisations apart from one - which you have to register with before you can race. It's very time consuming and you might not even get accepted. And then there are the hip problems which would stop you from racing anyway.
The "real" Snow Dogs (if you mean from the movie) were Siberian Huskies and Alaskan Malamutes - not a cross between the two.
If you want to race, why not visit some rallies (it's rally season!), meet some dogs and their owners, and get a healthy, KC registered pup.
