Betfred are offering free betting opportunities on men's and women's singles matches at the Olympics.
You can bet live in-play on Olympic Tennis at Betfred
You can bet on any men's or women's singles match at the Olympics and if your selection is beaten in a final set tiebreak, Betfred will refund you as long as your bet is between £5 and £250.
Bets must be placed before the start of the match. The offer does not apply to in-play bets.
This offer is available for the full duration of the Olympic event. Free bets will be credited to your account within 48 hours of your bet being settled.
This offer could definitely be worth taking when betting on some of the big servers in the men's singles draw. The likes of John Isner, Milos Raonic and Andy Roddick are regularly involved in final set tiebreaks and with Isner and Roddick in fine form heading into the Games (Isner won the Newport title a few weeks ago and Roddick picked up the Atlanta title last weekend), taking a punt on their matches could reward you handsomely.
You could also use this offer to cover your bases when betting on Marin Cilic's matches. The big Croatian is a dark horse to win a medal after showing some fine form on the grass last month, winning the Queens title and making the last sixteen at Wimbledon.
