D

Dam
The mother of a horse.

Dead heat
Where two or more competitors both qualify for an equal place.

Decimal prices
The price system mainly used for betting in mainland Europe and Asia. Odds are expressed as decimals (rather than fractions) and winnings including your stake. For example, £10 at 1.90 = £10 x 1.90 making a return of £19.00, including your stake.

Declaration
Leading up to the day of a race, owners and trainers have to decide whether or not to let their horses compete in the race. These are known as acceptance or declaration stages and every race has one five days prior to the race and another on the day before the race.

Derby
One of the five ‘Classics’ of the flat season in the UK, for three-year-old colts and fillies.

Distance
The distance of a horse race. Five furlongs is the minimum and the four and a half mile Grand National is the longest. Distance is also the margin by which a horse is beaten by the horse directly in front. This can range from a short head to ‘by a distance’ (even more than thirty lengths).

Dividend
This is the agreed payout or return on any bet.

Double carpet
Slang for odds of 33/1.

Doubling up
This is to increase your wager on a selection when especially confident of winning.

Down the card
This indicates races at the same meeting.

Draw
In horse racing, at the overnight declaration stage, all entries in a flat race are given a stall number from where they will start. This is known as the draw. Stalls are not used for National Hunt racing and, therefore, the draw does not apply.

Drift
This is where the price of one selection increases because of the lack of interest from punters or other factors.
