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.
