In general it is not. For the 2009 even there was a 1 hour special broadcast 6 months after the event on Speed. Outside of print and the interwebs this is not a well covered event. Most of the car mags will have a story on it as well. Canadian TV probably had some coverage. Jim Kenzie is a Canadian Auto Journalist that drives a MINI in the event.

And if you follow the link, the first words you'll see are: "What can I say - WE WON!" More to come. But here's a preview of the hardware we brought home....
I caught the Speed broadcast of the 2009 event, and I figured I has simply missed the earlier ones. Will keep an eye on their schedule in case they they do the 2010 event as well.
