Exceller's pedigree http://farm2.static.flickr.com/1059/533591447_a25192718f_m.jpg This beauty was the inspiration for The Exceller Fund
Exceller (1973 - 1997) is widely considered one of the best horses to race in the United States and not win a year-end championship. Despite his exemplary achievements as a racehorse, and his unique accomplishment in being the only horse to ever defeat two Triple Crown winners (Affirmed and Seattle Slew), Exceller is now remembered more for the tragic manner of his death and the horse rescue movement it helped inspire. Exceller was exported to Sweden and later killed in a slaughterhouse. 
Exceller won major stakes races in Europe, Canada and America, here is a list of his Major Racing Wins: Prix Royal-Oak (1976), Grand Prix de Paris (1976), Coronation Cup (1977), Grand Prix de Saint-Cloud (1977), Canadian International Stakes (1977), Hollywood Gold Cup (1978), Hollywood Invitational Turf Handicap (1978), San Juan Capistrano Handicap (1978), Sunset Handicap (1978), Oak Tree Invitational Stakes (1978), Jockey Club Gold Cup (1978).

Honours: U.S. Racing Hall of Fame (1999) and ranked #96 - Top 100 U.S. Racehorses of the 20th Century
Exceller ran best, like many European horses, "covered up"--deep in the pack early. In the late stages of the race he produced a powerful burst of speed and caught the leaders in the stretch. From a race enthusiast's point of view, Exceller's final quarter mile times are nothing short of amazing: he regularly sprinted the final quarter in under 25 seconds. His fractions of 23 2/5 seconds at the end of the Hollywood Gold Cup and Oak Tree Invitational is amazing when you consider that 23 seconds is a quick first quarter in such a race.
Exceller left behind 16 crops of foals in the United States, including 19 stakes winners and 40 stakes horses, none of them of his quality. His runners were headed by the fillies Slew's Exceller  and Squan Song , a grand daughter of the great Damascus. More info on Squan Song
