Just to come back to Allaho etc, I've now run the videos of that race and the 2m5f race on the same card from the first fence in the latter race.
With that race being a classy valuable handicap, I'd expect them to go strongly and, given how they were fairly well spread out early, I'd suspect it was a well-run race.
I'd also expect a G1 3m race to just about match it for pace.
It looks to me like the handicap was between four and six lengths faster over fences 2, 3 and 4 in that race and it was only on the run away from the stands, across the dirt path and on to the next that Allaho closed the gap down. After that, Allaho turned the taps on and over the next several fences pulled up to 15 lengths clear but from the fence before the home turn to the line the handicap was closing it down until it was only a couple of lengths at the line.
This would appear to back up my initial impression and why I asked the question what were the jockeys doing allowing Allaho a soft lead. They weren't going fast at all in the first mile and G1 chasers should have been comfortable at 2m5f handicap pace. It was the middle mile that decided the race. That was when Allaho injected real pace and only CDO could go with him.
I suspect, too, that to an extent the rest of the field weren't quite at their best, maybe the season catching up with them.
But Allaho turned it into a two and a half mile race and played to his own strengths.
Imvho...
