They say there are only two certainties in life, but bet365 have two more to add to that list for this week's Cheltenham Festival.

Best Odds Guaranteed on all races at the Cheltenham Festival

Exactly as it sounds, take a price on your selection and, if the starting price is bigger, bet365 will pay you out at the bigger odds.

For example, back Kauto Star now for the Gold Cup at 2/1 and if it drifts out to 5/2 and wins, get paid out at 5/2!

To celebrate this special week, bet365 have doubled their new customer offer to £200 free bets, providing you sign up between Saturday 7^th March and Sunday 15^th March.

To qualify for your £200 free bet basket, register with bet365 and place your first qualifying bet. You will then be entitled to a free bet to the same stake up to a maximum of £50 on a market of your choice - Kauto Star to win the Gold Cup perhaps?

Another free bet up to £50 is available after you've placed a further five bets with bet365, while third and fourth free bets are available in much the same way.
