If racehorses blew out candles on their birthday cakes, Perigo would be the only one with 15. Because while all New Zealand's racehorses celebrate their birthday today, only Perigo will be turning 15.
New Zealand's oldest competing racehorse is a worldwide wonder - horses racing at his age are almost unheard of in recent years.
There has been only one other in New Zealand in the past 20 years, thoroughbred Decoy Lad, in 1999.
And Perigo isn't just racing. He is still winning, at New Zealand's most competitive racetrack, Alexandra Park. He will race there again on Friday night. How rare is that?
It is roughly equivalent to a 53-year-old playing in the national rugby championship.
