[Danzig]

i think in general, a trainer works a horse prior to a race to get him to do certain things in a race. if you constantly ask a horse for speed, speed and more speed, that's what he'll give you in his races, til he runs out of gas. so a five f work, and a very fast one, will put a horse on his toes-which is what happened with funny cide.
it's somewhat like when they take the horses to under tack shows. they drill the fast furlong into them, and then you buy the horse, and have to essentially retrain them to learn to relax. so funnys work didn't show him relax, it showed speed. so he broke fast, fought the jock (a losing proposition for the jock) expended too much needed energy fighting the jock, and then finally gets set loose-or broke loose-and then had nothing left for the finish.
