Stride rate of the top 4 Derby finishers over the last five years measured over the final furlong of their last prep before the Derby. I think it's very interesting what this says.
2012; 1st - I'll Have Another 26.5, 2nd - Bodemeister 27.5, 3rd - Dullahan 26, 4th - Went The Day Well 27.5
2013; 1st - Orb 26, 2nd - Golden Soul 27 (taken from Derby itself since he was too far back in final prep to get a count), 3rd - Revolutionary 27.5, 4th - Normandy Invasion 27
2014: 1st - California Chrome 26.5, 2nd - Commanding Curve 27*, 3rd - Danza 27, 4th - Wicked Strong 27
2015; 1st - American Pharoah 26, 2nd - Firing Line 27.5, 3rd - Dortmund 26.5, 4th - Frosted 27
2016 - 1st - Nyquist 26.5, 2nd - Exaggerator 27.5, 3rd - Gun Runner 27.5, 4th - Mohaymen 27.5 (taken from Fountain of Youth since he was too far back in Florida Derby)
* Commanding Curve finished 3rd in the Louisiana Derby that year. The horse that beat him that time, Vicar's In Trouble, had a stride count of 32 over the last furlong in winning the race. Vicar's In Trouble then went on to finish last in the Derby that year.
None of the top 4 finishers in the Derby over that span had a stride count in the last furlong of more than 27.5 in their final prep save for maybe Mohaymen. I don't know about you guys, but I think it could definitely mean something going forward into the 9F preps and into the Derby itself.
