In simple terms, a handicap mark is the official number used to decide how much weight a horse carries in a handicap race.
The higher the mark, the more weight the horse is asked to carry. In theory, this is supposed to level the playing field and give every runner a fair chance.
That is why handicaps are so interesting from a betting point of view.
The market often focuses on obvious recent form, but the real question is whether a horse is well treated, harshly treated or still has enough room to improve from its current mark.
At Turf Talk, this is one of the most important parts of our analysis, especially in the bigger handicaps where the ratings can help separate a well-handicapped runner from one that may now be vulnerable.
