Got this from the Fantasy website I use.
Watching F1 Live
It's been getting more expensive to watch the races live, the only real option until recently has been Sky TV, their cheapest F1 package is £27.50 a month with an 18 month contract.
You can watch for free online if you can find a reliable stream, but there is another option that was launched quite recently.
NOW TV lets you watch the races live (It's the Sky F1 feed) for just £7.99 per race. It's the cheapest, most reliable option if you combine that with the free to view races on Channel 4. You don't need any expensive equipment (you can watch via a games console for example) and there is no contract. Click below for more details and to sign up.
For a limited time NOW TV are doing a special offer on a full F1 season pass, this lets you watch ALL races and qualifying sessions live plus the practise sessions. It's discounted to £150 for the full season - F1 Season Pass. The offer expires on 25th March so get in quick!
personally I would not pay that, if I did not have Sly Sports already.
