Why the Grading System Matters
Look: every trainer knows the difference between a rookie sprint and a seasoned marathoner. The UK grading system is the GPS that tells you where a dog sits on the speed spectrum, and missing it costs you more than a missed start.
Quick Overview of Classes
Here’s the deal: A1 is the elite, the crème de la crème, the dogs that shave milliseconds off the track. A9 sits at the bottom, the newcomers still learning to chase the lure. The ladder isn’t linear; it’s a jagged ridge where each step demands a specific performance band.
A1 – The Pinnacle
These are the champions that make headlines, the ones you see on TV. They run 480-meter sprints in under 28 seconds, and their times are rock-solid. No room for error, no cushion for a bad day.
A2 to A4 – The Upper-Mid Tier
Dogs in A2-A4 are strong, consistent, and often on the cusp of breaking into A1. They clock 28-30 seconds over the same distance, and trainers treat them like gold-mines, polishing every nuance of their stride.
A5 to A7 – The Development Zone
These are the workhorses, the dogs that need careful placement to avoid burnout. Times hover between 30-32 seconds. You’ll see them shuffled between heats, gaining experience, sharpening tactics, and building confidence.
A8 and A9 – The Beginners
Newbies, first-time racers, or dogs returning from injury. They might be slower than 32 seconds, but they’re the raw material for future stars. Patience and proper grading keep them from being crushed under the pressure of higher classes.
How Grading Is Determined
And here is why the system works: every race result feeds a database that calculates a dog’s average speed, variance, and consistency. The algorithm nudges a dog up or down a class after each run, ensuring the grading stays fluid, not static.
Trainer input also matters. If a dog shows a sudden burst of speed in training, you can petition for a re-grade. The committee reviews the data, and if the numbers back it up, the dog jumps a class.
Practical Tips for Trainers
First, never enter a dog in a class that’s too high; you’ll waste its confidence. Second, keep meticulous records of each run — time, track condition, weather. Third, use the official grading calculator on the Greyhound Board website; it’s the only reliable source.

Bottom Line
Don’t gamble with grades. Treat the class as a living document, adjust tactics on the fly, and you’ll keep your dogs racing at their optimal level. Now go out and get those dogs the right heat, or you’ll be the one left behind.
