Ladbrokes are offering double winnings up to £25 if your horse wins the 14:30 Ascot. The extra winnings are paid as a free bet

Option 1 - Bet and hope ~ £18 potential profit
*Choose a horse in the 14:30 Ascot race on tuesday
*Work out the amount you need to stake on the horse by doing this:-
25 / (back odds - 1)
For example if the horse is odds 4.0, you need to stake 25 / (4 - 1) = 25 / 3 = £8.33 stake
*After you've worked out your stake, stake this amount on the horse and lay it as normal
*Hope your horse wins for the free bet

Option 2 - Lock in ~ £4 lock in
*Choose a horse in the 14:30 Ascot race on tuesday
*Open Oddsmonkey's Win Bonus Calculator here
*Fill out the calculator as follows:
The bookmaker is offering extra winnings as a free bet
The stakes are limited to £(blank) and/or the bonus is capped at £25
The boost is a fixed value of £25
I expect to retain 80% of the free bet
The back odds are (your back odds)
The lay odds are (your lay odds) and I pay (your commission %)

The calculator will now tell you how much to back and how much to lay. It's not a simple case of backing £25, as it's a boost up to £25. So back whatever the calculator says to, and lay what it says to. If your bet loses you'll make an instant profit. If it wins you'll make a slight loss but will receive a £25 free bet which you will then profit from.

*No min odds
*Max free bet £25
*14:30 Ascot only
*Free bets credited within 24 hours
*Free bets expire within 24 hours

This offer combines William Hill's daily price boost with their 2Clear promotion to give you a risk free chance at a £100 free bet, and also to make a few quid on the qualifying bet!

*Open the list of horse race meetings on mobile site here
Boost will only show on mobile site, but you can access it on desktop by clicking above link
*Click on any eligible race (listed below)
*Find any horse with close back & lay odds
*Add horse to betslip, and click "boost" to boost the odds
*To work out how much you need to stake for the maximum £100 refund, do 666 / (original odds -1). We use 666 as 15% of this is £100, so we need to "win" £666 to get the full £100. You can do less, i.e. 333 for a £50 free bet and 167 for a £25 free bet.
For example, a horses odds are 5.5 boosted to 5.9. You need to do 666 / 4.5, which gives a £148 stake for the maximum £100 free bet
(You can bet up to £200 on the horse with the boost however will only receive a max £100 free bet)
*Place bet and lay at exchange

You should instantly profit from the boost if you've made the back odds higher than the lay odds

If the your horse wins by 2 or more lengths, you will receive a free bet of 15% up to £100.
