Money Back Offer (15:35 Doncaster) – Genting Bet

Posted by Matt (administrator) Matt
Start Time: 12/09/2020 15:35

There’s a big day of racing at Doncaster on Saturday and you don’t want to miss this Genting Bet offer! Simply place a single bet of £10.00+ on the 15:35 at Doncaster and get a £10.00 free bet if our selection loses and Pyledriver wins the race. Translated into matched betting terms, this gives us a potential profit of £7.00 and here’s how…

Key Terms:

  • We must place a single bet of £10.00+ or £10.00 each way on the St Leger.
  • Our bet must be placed before 15:35 (race-off) on Saturday 12th September 2020.
  • If our first bet loses and Pyledriver wins, we’ll get a £10.00 free bet.

Qualifying Bet:

If you’d like more information about qualifying bets and how they work, please see my Qualifying Bets Guide.

For our qualifying bet, we need to back and lay any horse other than Pyledriver.

Having looked at the odds available, we could place our qualifying bet on Santiago.

At the time of writing, laying our bet at Betfair gives us the smallest qualifying loss.

Place £10.00 on Santiago @ 3.75 = Potential profit of £27.50

Lay £9.19 on Santiago @ 4.10 = Potential liability of £28.48


Let’s have a look at our potential profit/loss for the possible outcomes…

Outcome Bookie Exchange Extracted Profit/Loss
Santiago wins +£27.50 -£28.48 £0.98 loss
Pyledriver wins -£10.00 +£9.00 +£8.00 £7.00 profit
Another horse wins -£10.00 +£9.00 £1.00 loss

So, if Pyledriver wins, we’ll make a nice profit of £7.00! Any other outcome and we’ll lose a maximum of £1.00. Risking £1.00 to make a profit of £7.00, gives us effective odds of 8.00. So, given that Pyledriver is odds of just 4.00 (3/1) to win the race, this is a profitable offer in the long run.

If eligible, free bets will be credited within 4 hours of the race settling and will be valid for 3 days. Free bet stakes are not returned with any winnings.

If you’re unsure how to convert your £10.00 free bet into £8.00 cash (80%), please see my Free Bets Guide for a walk-through of how it should be done.
