He has raced with that nasal strip all of his life-—as many other horses have. It is a product that has been out on the market for about 15 years.
Not in the Belmont they didn’t.
And every other owner who’d make a big deal out of the nasal strip would be telling me that they’re concerned with their horse’s wind.
Secretariat didn’t use one. Based on his time of about 2:24 and Tonalist’s time of roughly 2:29, Secretariat would have beaten Tonalist by about 20 lengths and California Chrome by about 26 lengths, and that without a nasal strip.
