Name some top-notch horse-racing events in the UK.

Horse racing has a long and celebrated history in the UK, evolving from informal local races to the highly organized and popular sport we know today. Royal Ascot, for example, dates back to 1711, founded by Queen Anne, and it's not just about the horses; it's a major social event, known for its strict dress code and royal patronage. The Scottish Grand National, first run in 1858, is another key event, showcasing the best in steeplechase racing. These races are steeped in tradition, attract huge crowds, and are significant events in the British sporting and social calendar. While the Six Nations Championship is a major rugby tournament and The Open Championship is a prestigious golf event, they simply don't belong in the category of horse racing. So, when you think of top-tier horse racing, remember the regal atmosphere of Royal Ascot and the challenging course of the Scottish Grand National.
