Mares in heat system?

[smk415]

Ok, haven't been here for a long long time due to too much work and not enough playtime. Do I miss the racing yes I do, I miss reading the post, looking up data on horses, jockeys, owners, trainers, seeing when it ran lto, was it raining, was the running hard, Its just too much time I cant afford to give to it anymore

Anyway on to an idea I had, during a conversation according to my missus who was a long distance runner, women during their period can produce their best running times so i looked it up.......
The menstrual cycle and exercise
look under better performance down the page.....

so then I came thinking what about horses and can it work for the mares?
but needless to say I cant find out any info about horses running faster but it looks like this system could only work in cycle about every 21 days during the early spring and summer. They will come into heat for about a week each 21 days.

So if anybody knows any stablehands can they ask them do their mares actually run when in heat or is it too much of a danger to the other stallions and they are not allowed on course.

I know with cows that when they are in heat, a bull will go thru a brick wall just to tap dat ass, and I can see it being the same for a stallion,
but it may prove an interesting subject..
