Yes, camel jockeys are camel racers. The problem is these are not grown men, but little boys who are kept basically as slaves.
They are almost always under ten years old and live in often horrible conditions. The kids are often injured or killed.
They are supposed to be using robot jockeys next year in Dubai.
(I learned all this on FR of course)

Thanks for the information, texasflower, disturbing as it is.
