How old are racehorses when they start training?

Answer 1

It really depends on the trainer, but most are starting training when they are about 2 or 3 years old so they can get their prime years on the actual race track. But there is the yearling race in which 1 yr old horses race.

Answer 2

The minimum is one year old. You can't really start younger than that because the saddles and riders are too heavy for them. Plus they need time to grow into their long little legs.
