Dynamic horse racing factors are those which change according to how the race shapes up while it is being run. They may change in a moment and most success or failure depends on those factors. An example is pace. Another factor that is both dynamic and beyond the control of the human population is the weather. You may handicap the races the night before and expect a fast track based on a weather forecast. Like most weather forecasts it is nebulous and sure enough, the track is sloppy by the time the race is run.
The obvious solution to that problem is to handicap for both a wet and dry track. That will take more time and effort, but may pay off in the long run. Trying to prepare for changes is the key to mastering dynamics as well as you can. Pace scenarios that develop or disappear due to scratches is perhaps one of the most frustrating aspects of being a serious horse player. Then of course, there is always the matte of track biases that appear and disappear.
A good angle for handicappers is to write down the most solid and concrete of factors first and then work your way to the dynamic and easily changed factors. If you think a horse is likely to win, ask yourself which dynamic factor could cause the horse to lose and perhaps help another to win. For instance, if the main threat is breaking from the outside and your pick is on the rail, a slow track on the inside path could negatively impact your pick and help the contender who will race from outside.
When you go to the races you’ll have to watch the races and determine how the track is playing. If the rail is dead, it’s time for a change in plans and that outside runner may now be your best bet. Dynamic factors are situational and therefore the horse player has to be willing to adapt. Believe it or not, many of the bets you’ve lost over the last year were impacted by dynamic factors. Think back to the races you lost and why the horse you backed didn’t win. Was the pace scenario different than the one you predicted? Did you find out there was a bias after the race?
The health of race horses is subject to change without notice. After a big race the trainer may announce that the horse had colic just days before the race but the vet gave it a clean bill of health so the horse ran. How would that information changed the way you wagered? Take time to consider as many dynamic factors as you can and do your research before the race to nail down as much as you can. It’s still horse racing and anything can happen, but the more you know about the dynamics of the race, the better your chances of winning.
