When a bettor is organized and tracks as many horses as possible running at a particular venue, using factors like race history, venue, running surface, and track conditions, that bettor can make more informed decisions and bet the percentages for the best chance of success. Horses that win most often in the top category are the obvious favorites, unless they happen to be running against each other. Races with two or more top horses can be good opportunities for exacta box and trifecta box wagers. Weather and track conditions also affect betting options, and those conditions can be tracked as well. If it is cold and rainy and the track is muddy, there is likely a horse that performs particularly well under those conditions, potentially up against horses that run strong when conditions are ideal but struggle when the weather and track surface turn poor.
