THE racing and bloodstock industry has undergone a transformation since I first started following it in the early 1980s, and one of the changes is in how the top horses are campaigned. Now many thoroughbreds build up substantial amounts of frequent flyer miles, taking on the best in multiple countries, on several continents, and sometimes notching up massive earnings totals and a global fan base. Highland Reel, who is about to start his new career at Coolmore Stud, was an epitome of the modern racehorse.
