No one has ever doubted Fame's stamina, its the pace they doubt. His pace was evident to me in the Irish Derby.
But surely sustaining a strong pace
is stamina?
Most
top horses are pretty well capable of hitting the same top-speed. Some can get there more quickly than others (acceleration - often confused with pace) where as others can sustain that top-speed for longer, (the last one to start slowing down etc stamina in any other language).
It stands to reason that off a slow pace, the horse blessed with the greater acceleration will beat the one with less. What tends to happen is they open up a quick gap in order to reach that top-speed and are then able to hold it. Once achieved, both horses would now be travelling at pretty similar levels, with the pursuer unable to make inroads into the leader even though both are doing the same speed. You could see it graphically in the days of turftrax when they plotted the winners performance against the field average. George Washington's Guineas was the clearest example of it, where he put 2L's between himself and the field, and then maintained that advantage through the remainder of his plot. He never pulled away, (in fact they came back at him fractionally) but with all the horses travelling at pretty well the same final speed, and possessing similar levels of stamina to see the race out, it was his acceleration that decided the issue.
Off a fast pace though, it's the horse that is able to sustain his effort through the sections that tends to prevail by simply opening the gap incrementally. Again they can all hit the similar top-speed, but some can only manage it for half a furlong, where as others can draw on their stamina to keep hammering through the sections at the same pace for much longer. Hawk Wing and Ratki's Lockinge would be examples where the plot simply extended. Although people call these fast horses and say its pace that's won the day, it's a slightly incorrect assingnation I feel, as what you're really witnessing is the horses ability to sustain that level of performance over a longer distance than his rivals (stamina).
All of this pre-supposses that Fame and Glory has the pace necessary to sustain it of course, as there's no shortage of horses who get a trip at a slow pace, but that's not stamina, that's just lack of class.
What you saw at the Curragh isn't likely to be pace as your suggesting, but more likely to be stamina, and that regard the Curragh won't necessarily have cast any new light on the horse (as you accept that his stamina isn't the issue). Once he got up to top-speed it was his stamina that continued to extend that lead, not his pace. He did however take his time to get there, and with 2 furlongs less one feels he needs to have it cranked up for him from the moments the gates open.
