Weir began his career as a trainer in 1884 and in 1893 won 150 races. Success led to a move in 1903 to New York to compete at the big tracks at Sheepshead Bay, Gravesend, Brighton Beach, Aqueduct, Jamaica and Saratoga. There, between 1903 and 1907 he won 217 races and earned $294,957 (adjusted for inflation: $8,212,083 in 2019).{{cite web|url=https://drf.uky.edu/catalog/1900s/drf1908012801/drf1908012801_1_13 |title=Weir's Extremely Successful Career |publisher=Daily Racing Form at University of Kentucky Archives |date=1908-01-28 |accessdate=2019-03-11}}
