Someone help me out ???

it must be simple math but how many beyer points does it take to equal 1- Mile Per Hour.

on an average obviously it would not be exact

but if someone was comparing 35 mph or some other speed, converting Feet per second to MPH.

And using 8 feet per length.

And a beyer is around 2 or 3 points per length

How would you compare/total the two.

Well, let's see... if a horse covers 6fur in 1:12, that's 3960 feet in 72 seconds, which works out to 37.5mph. A horse that covered only 3854 feet in those 72 seconds would work out to 36.5mph, which is the 1mph difference you're looking for. Using your 8 ft per length, this difference works out to 13.25 lengths, which would be anywhere from 4 to 6 Beyer points based on your rule of thumb.

Sounds good. I never understood the need for feet per sec or mph conversions. One unit of measure should be just as good as the other for comparing speed.

Your looking for another 200+ post thread aren’t you…LOL :D

Very true, speed is speed is speed, no matter the scale or method of measuring.

Eight feet per length in full stride? What are these? Shetland ponies???

The reson I asked was to be capable of "ballparking"

Adding FPS converted into MPH into the BEYER Fig the horse had.

raw MPH plus varient adjusted Speed Figure improves , I just wanted to "square up" the comparison...scale...of the two, roughly.

that way I have the raw and the adjusted one from just the clock one from a person looking at the results and making a fig.

Dan, I wouldn't touch that subject with a ten foot pole -- or is it eight?

the velocity numbers are particularly useful to me when evaluating turf runners.

This also applies to polytrack, although not as well if the standard is unknown and the opportunities and sample is so small. It was decent at the end of the hollywood cushion meet.

You look at the last quarter, and the last 4 furlongs (adust this to about where they start to sprint for home, last4 is usually good for a 8.5,9furlong race). For kicks even look at the last furlong if possible.

youtube is handy for catching some imports and pretty easy to do the velocity off of the poles and field markers...

It is more usefull of judging whether a horse has a talented kick or not, than making a tell-all speed figure. You want the velocity to agree with your visual impression.

Molengao was a good one recently in a Lava Man race 2 or 3 back. His prep was visually impressive with the announcer literally screaming his name at the end. Molengao's late-kick velocity was not all that impressive in the prep race. All the wise-guys had him to upset Lava Man.

Velcoity is useful when the distances arae different.
Which is faster, 2 furlongs in 24.2 or 3 furlongs in 36.1?

I'm not saying it's 8 feet or 12 feet, but why would it matter if they're in full stride or standing still? Either way, the distance from nose to rump isn't going to change :confused:

Okay, this makes sense. If your analysis is based on real time. I see the world through BRIS's pace figs E1, E2, and LP.

another good example of a visually impressive effort that doesn't quite match the velocity is Grasshopper's prep last out.

Street Sense and Sightseeing came home much faster in raw velocity.(without doing the math CPWest may have as well it was close...) The Allowance and the JimDandy were a day apart and I honestly don't have specific track weights/varients in front of me to compare surfaces.

Grasshoper appeared to come home so fast due to the group he was running with. The same group ran another clunker yesterday in the 6th.
This doesn't take away from the fact that Grasshopper finished in full stride and was physically impressive. He didn't appear tired.

All It does say that unless the track was much slower for his allowance, Grasshopper was not as fast in the final furlong as his big competion 26 or 27 days ago. Bris LP #s aside.

So you're timing them when they're standing still? It's the distance from the point where the front feet touch down to the point where the front feet touch down on the next stride. It will vary from horse to horse but it will be a lot longer than 8 feet.

This is where I came up with 8 feet.
I respect this author.

This explains the 8 feet per.

Doesn't matter what a horse measures - it matters what they use to call beaten lengths.

I know using 8 feet instead of 10 feet has proved better in my numbers. Someone posted about the pole distances being 8 feet and that was how they called BLs for charts? Not too long ago, but I couldn't find it searching today.

I've seen 8,9,10, and 11 feet used. Sartin used as few as 4 for fractions.

Remember, it's now how long it is, it's how you use it. :eek:

Isn't that called the "stride"?

"Timing them"? Time has nothing to do with how long a length is. You're describing the length of a horse's stride, not how long a length is. If a horse's nose is up against the rump of the horse in front of him, he's a length behind... doesn't matter that they're covering more than twice that distance with each stride.

Lengths per Furlong x Furlongs / Time

66 x 2 / 24.2 - 4.5 x 100 = 95.5 -- 66 x 3 / 36.1 - 4.5 x 100 = 98.5 ;)

660 feet in a furlong



2 furlongs in 24.2 or 3 furlongs in 36.1?



1320 feet divided by 24.2 seconds equals 54.55 ft/s

1980 feet divided by 36.1 seconds equals 54.85 ft/s


thought it was rhetorical question
