Sainfoin was the winner of the first ever "Arab pony race." Pony races were held at Northolt track in England from 1923 to 1940 for horses under 15 hands, and starting in 1929 some of the races were evidently limited to Arabians. Sanfoin is featured in a detailed Getty image (copyrighted, expensive) titled Arab Pony Racing Northolt. The caption reads: "The Arab pony Sainfoin about to win the first ever Arab pony race being chased by the Maid of the Moot who eventually finished third, the race being held at Northolt park north west London, England 25th September 1929." For more about pony racing, see Northolt Park Racecourse history and a brief YouTube video showing the last day of pony racing when Northolt closed for the season in 1934.
