This Saturday Betfair are offering you the chance to start a free bet streak by placing a £10 bet on any sport on the Betfair Exchange.

Even if that first bet loses, you will be credited with a £10 free bet to begin your streak. For every winning £10 bet you have for the next seven days on the Befair Exchange, we will credit you with another tenner to keep that streak going.

We have collated some of the best tips from our horse racing tipsters to inspire you to get your streak underway by placing your first qualifying bet this Saturday, but before we get into those, let us take you through how to get involved.

How does Betfair's Free Bet Streak offer work?

1. Opt-in on the Betfair Exchange promo page or bet banners on the Exchange homepage
2. Place a £10 bet on any sport on the Exchange on Saturday 12 October. Your first cash bet will qualify for the offer.
3. When your qualifying bet settles (as a winner or loser), you will be credited with a £10 free bet on the Exchange within 24 hours.
4. Your Free Bet Streak begins with your first £10 free bet, to use on any Exchange market (minimum odds apply). The way to keep the streak going is to keep on winning.
5. If your free bet wins, you will earn another £10 free bet, alongside your winning returns. If you lose, your streak is over.
6. You will continue to receive another free bet every time your free bet settles as a winner for a maximum of 7 days after the initial free bet has been awarded.

Remember, the tips below are related to horse racing, but you can place a bet on any sport on the Exchange to get involved!

So grab your mates, test yourselves against the best tipsters in the business, and crown yourself with the longest winning streak of all you take-on!

Saturday horse racing tips and insight from our very own...

Mark Milligan - 13:50 Newmarket: Shackleton

The 1m 2f Group 3 Zetland Stakes is a proper test of stamina for two-year-olds and I'm confident that Aidan O'Brien's Shackleton can see it out better than his six rivals.

This son of Camelot looks a stayer in the making and he was off the mark at third time of asking over 1m 1f in maiden company at the Curragh just under a fortnight ago.

He made all that day and found plenty for pressure once coming under a ride in the home straight, never stronger than at the finish and looking as though he'll be well served by this trip and beyond.

Prior to getting off the mark, Shackleton had finished runner-up to Tennessee Stud at Thurles and that form was franked when the winner went on to run a fine second to Hotazhell in the Group 2 Beresford Stakes on his next start.

In terms of the opposition, it may be the Wathnan Racing-owned Dunamase who emerges as the biggest threat.

John & Thady Gosden's juvenile cost a packet at the sales and duly got off the mark at the second attempt on the all-weather at Kempton last time.

He'd looked green at Sandown on debut but had clearly learnt plenty form that and there should be more to come as he gains in experience.

Daryl Carter - 14:40 York: Strike Red

Strike Red - 7/18.00 on the Betfair Sportsbook - won this race two years ago, and he arrives in much better form than his latest figures suggest.

He was last seen in the Ayr Gold Cup, finishing tenth, but he did the best of any single figure draw, with Kings Lynn next best in 14th. He was poorly drawn in a race favouring high draws, highlighted again by the top three drawn 19 or higher. He did well only to be beaten fourth lengths there, and it was the same story from stall three when he caught the eye at the Curragh on his penultimate outing.

Today, the angle is the draw. Low-drawn runners have dominated at York this season and in this race, with only one winner birthed higher than nine in the past ten years. The stalls are situated on the far side of the track, which doesn't help those not a fan of the bias, but it helps Strike Red in stall nine.

He is handicapped to have a say, and he won't mind the soft ground expected. There's lots to like, and at 7/18.00 or bigger, he can gain a deserved victory this season.

Ryan Moore - 15:00 Newmarket: The Lion In Winter

He is a lovely uncomplicated clot who was impressive on debut at the Curragh - the third that day, Ides Of March, has done plenty for the form of that race - and he took another step forward when beating subsequent Royal Lodge winner, Wimbledon Hawkeye, in the Acomb at York.

Godolphin look to have a strong hand here with the Middle Park winner, Shadow Of Light, stepping up to 7f for the first time and Ancient Truth is a nice colt who was impressive in the Superlative on the July course.

It's a competitive race but my colt sets a decent standard.
