There's usually somewhere between 33-50% (or more.....varies every year) of the horses that that start the race don't finish it.
By far the most common reason is they fail a vet check and get pulled.
Then there are times when the rider will turn back or stop because they don't feel their horse should continue.
And of course a horse can die in an accident, but that's the least common reason for not finishing and doesn't often happen.
