Besides being a horse racing lover, i am also a huge fan of road cycling. (Like the Tour de France) I love watching seriously trained athletes fly at high speeds using nothing but themselves as the motor. One of the best sights in the sport is when there is a sprint finish at the end of a stage. If the team has a strong finisher for the sprint, the team might consider setting up a lead-out train. This consist of one or more riders riding in front of the sprinter to ensure a high pace while providing a wind break. One of the best at doing this team Liquigas. (if you have ever seen any road cycling, they are the Neon yellow wearing team)
Here is a video to show what i mean:
Note how at 1:16, the neon yellow jerseys get in position, and how they lead out the their sprinter, Daniele Bennati, who wins this particular stage.
The reason i bring up this up is that Horse racing use to employ similar tactics by the use of the rabbit. Horse racing has a history of using rabbits in races to ensure a strong pace. Usually the rabbit is a horse who is owned by the same owners as the star of the owners. There have been many great examples of rabbits over the years. Damascus had Hedvar; Gallant Man had Bold Nero; Buckpasser had Great Power (Durso, http://tiny.cc/d6lx8 ) Even in more recent times, Breeders' Cup Turf winner had a rabbit employed in either Shake The Bank or Icy Atlantic. The practice is still very prevalent in Europe.
Winstar Farm is the unique position of being able to reproduce a version of the "lead-out train" for their Derby horse Endorsement (and Drosselmeyer if were able to get in to the Derby.) With three confirmed speed types in Rule, Super Saver and American Lion, in theory they could set it up so that one of their horses goes to the lead for the half mile, then have another take over for half mile, then have the last one take over for an eighth and give Endorsement a perfect set-up to take over for the final furlong.
Now, i know that there are several problems with this idea: That the pace set-up will not only help Endorsement, but every other non-speed horse in the field. That it might be considering "unethical". That using the horse as a rabbit is not good for the horse. Those concerns are valid and i really cannot say that the do not bug me a bit as well.
But this is just an idea that if nothing else, would look rather cool to see as the head down the backstretch the first Saturday in May, the Winstar Train rolling along.
