There's an article on the history of the race, some nice photographs, all the previous results and loads about this year's crews. All that's left is to book your seat for Sunday in front of a computer and enjoy!
You are right, Greg, the best and easiest way to watch the races is to sit in front of a computer as this is not really a spectator-friendly event to watch live.
