I saw it either on the Al Kass or on the AD Sports channel (I'm pretty sure it was AD Sports) the other night while flipping through, but don't remember the time
I'm not sure if there is a set schedule, but Camel racing is on fairly regularly on both AD Sport and Al Kass from October through April. I believe the broadcasts are live (at about sunrise in the Middle East) so it is prime time in the US. KTV seems to be a little less regular, but they sometimes have English announcers.
I did some research on camel races last year. The jockeys are mechanical robots sort of. They used to use children...child labor laws probably ended that
