About: John Barham Day

John Barham Day (1793–1860) was a British jockey and trainer. For much of his career he was usually known simply as John Day; when his son of the same name rose to prominence, the older man was referred to as John Barham Day, John Day, Sr. or Old John Day.

In the mid-1830s he set up as a trainer of racehorses at Danebury near Stockbridge. He established a reputation as a shrewd and skillful handler of horses and specialised in landing betting coups. Horses trained by Day won seven classics between 1838 and 1854, during which time he was regarded as the leading trainer in the South of England and the main rival of the Yorkshire-based John
