Here's why:
* Proper Nouns: "Finals" is part of the official name of the event. It acts as a proper noun, which means it refers to a specific and unique entity (the competition). Proper nouns are always capitalized.
* Event Names: In event names, even if the word "finals" is not the first word, it's typically capitalized because it's considered part of the official title.
Therefore, the correct way to write it is "National Double Dutch Finals."
