One Turn Route Races
Most route races (1 mile and longer), are raced around two turns. But, there are exceptions because some tracks have chutes in the backstretch and therefore can run one-turn route races. This is important to note because one turn route races are generally faster than two turn races, both in early pace and final time.
Top Mud Sires (wet track sires and pedigrees)
Horses with these names in their pedigree should like off tracks. This includes sires, dam sires, and broodmares. In some cases I've listed horses from similar families. For instance, Grindstone/Birdstone, Machiavellian and Street Cry. Relaunch (In Reality) is one of the most famous mudders so I also have other horses like Bertrando and Officer on the list, because they are from the same line:
Pandy's Top 10 U.S. Thoroughbreds (based on horses that I saw race)
Of the horses below, I saw all of them in person except Zenyatta and Spectacular Bid. On a list of the top 10 or 20 horses of all time, and horses that I did not get a chance to see race, I would definitely include Citation, Man o'War, Kelso, and Dr. Fager, and others merit serious consideration. Of the European horses, Frankel, who recently retired undefeated in 14 starts, stands out to me and might be the best turf horse that ever raced.
For pure speed, I feel that Secretariat was
horse I ever saw, especially at the classic distances. Seattle Slew, Zenyatta,
and Ruffian were also extremely fast horses. Seattle Slew and Ruffian just ran
horses off their feet with blazing early speed. I saw Ruffian twice in person
and I've always felt that she was the fastest horse I ever saw up to a mile.
Zenyatta was undoubtedly the fastest finisher I've ever seen. Since it's much
tougher to run fast late than early, I feel that Zenyatta is probably right
around the level of Seattle Slew and Ruffian. Yes Ruffian and Seattle Slew ran
faster races and early fractions, but that's because they raced on the pace.
Zenyatta was a deep closer so she did not have control over the final time, she
ran as fast as she had to while winning 19 of 20 starts.
