I just checked and the video plays fine for me. Question: are you signed up under +plus? This video is under our "pay wall" and you'll need to be a current subscriber in order to view this particular race video.
If you are a subscriber and it's still not working for you, please verify that your browser has the latest update. I'm watching it on the latest version of Chrome and it's working fine.
