is a United States harness racing
event held annually for three-year-old trotting standardbreds. The race is named for the famous trotting horse, Hambletonian 10 (1849-1876), from whose four sons, the lineage of virtually all American standardbred race horses can be traced. It is the most coveted North American race for trotters; among races for pacers, only the Little Brown Jug
is as prestigious.
The Hambletonian is the first, and most prestigious event in the United States Trotting Triple Crown races. For many years the race was held at the track in Goshen, New York then for many years at Du Quoin, Illinois and today at the Meadow Lands Racetrack in New Jersey.
