I have used speed figures over the jumps for the past 30 years or so. The only type of race they are worth utilising in are in Novice Hurdles in my opinion. That type of event has unfortunately now become a nightmare until around January. The advent of Bumper horses, Point To Pointers, French Breds being run with no Hurdle form to go on( and therefore impossible to equate with those that have run in hurdles) make it very difficult. Once we are in January, more runners have speed figures to compare in a race and you have more of a chance. However, the one area where they are completely valid and worthy of study are in Juvenile Novice Hurdles where the only other thing to consider is Flat form. Due to the All Weather, a lot of horses that used to go hurdling as 3/4 year olds are more likely to stay on the Flat. This has reduced the number of Juvenile Hurdles being run. However, I do know that backing runners with good speed figures in these events are profitable provided you use a reliable source.
