Gun Runner was one for the money in 2018, and then he was gone. The 2017 Horse of the Year was kept in training as a 5-year-old long enough to win the Pegasus World Cup at Gulfstream Park on Jan. 27, in a conclusive 2 1/2-length victory over 3-year-old champion West Coast, to put $7 million worth of icing on an exemplary career that touched parts of four seasons.
Once the Pegasus was in the books, Gun Runner entered stud at Three Chimneys Farm in Kentucky, along with his heady bankroll of just under $16 million.
