Oh dear...

...the race starts well. Starts.

Then a jockey comes off, the horse decides to continue without him until he has an opportunity to leave the premises.

Then another horse decides to run out and jump over the rail instead of the fence.

Oh, that loose horse from earlier is back.

Another jockey comes off. Now two loose horses on the course, acting as hazards to navigation.

We don't see the third one come off.

But...yeah. It's a novice race, I suppose that's their excuse (nobody appears to have been hurt). Commentator has some fun pointing out that most of them can't go in a straight line...
