There is a difference between show Whippets and coursers, but I wouldn't let it stop you. The coursers have a thicker bone mass. You can really see the difference in the occasional Whippet flat racer that you see. The key is to take the training very slow. Lots of walking, jogging and stretching. There is a slight chance that a show style whippet could be more injuriny prone then a coarser. because of structural breeding, but again I wouldn't let it stop you. Horses are the same way. I have made many beautiful and agile jumpers from racers, it just takes care and training. You should take time to read up about the kind of injuries that can occur, just so you have that knowlege. It's hard to completly escape broken toes, skin lacerations and ACL injuries in our breed even without sports. It's because when our guys play, they play HARD and they don't quit. I think we have the Lacrosse players of the dog world

The other thing that you really want to know alot about when doing canine sports is obedience, especially recall. Coursing is done in an open field, many times without a fence, so you have to be really sure that you have ful control to bring him back. I think that this is where many coarsing dogs have the edge. The breeders really breed sport dogs a little bit more for brains then show dogs. When my girl's litter was born, her breeder said he noticed that they were alot smarter then the other litters that he had bred in the past. Later on, I spoke with her Dad's owners and they said that the intelligence was in the coursing line. Anyway, as soon as I see them again I'll ask them if they know how you can get started.
