What these words mean

Underrated horse

We think this horse has a better chance than the bookmakers' odds suggest.

Our top pick

The horse with the highest TrackLab Score in the race.

TrackLab Score

Our model's estimate of a horse's chance of winning, as a number out of 100. The scores in a race add up to 100.

Ground

How the going was on the day, from Firm (hard and dry) to Heavy (very wet and muddy). On all-weather tracks it's Standard, Fast or Slow.

Race level (Class)

From Class 1 (elite) down to Class 7 (lowest).

Group, Grade and Listed

The top races. Group 1 on the Flat and Grade 1 over jumps are the highest level, then 2 and 3. Listed races sit just below.

Handicap

The handicapper gives better horses more weight to carry, so in theory they'd all finish together.

Maiden

A race for horses that haven't won yet.

Novice

A race for horses that are new to this type of race.

Chase, hurdle and bumper

Chase: jumps over fences. Hurdle: jumps over low hurdles. Bumper: a flat race for young jump horses.

Distance (m and f)

m is a mile and f a furlong, about 200 metres; 8 furlongs make a mile.

Each way

A bet that pays out if your horse wins or finishes in the top 3 (how far down it pays varies by race). It is really two bets.

Weight

How much the horse carries, including the jockey. 9st 5lb means nine stone five pounds.

Jockey claim

An apprentice jockey can claim a weight discount, so the horse carries a little less.

Headgear

Blinkers, visor, cheekpieces, tongue tie, hood and eyeshield change what the horse sees or feels.
