top three horses

many of you have done this

There are 25 horses and 5 race course. that means you can run atmost 5 horses in one race.

What will be the number (minimum) of races required to find the top 3 horses (top means which runs fast)

Those who already know this leave it for sometime :)

ok that was the first hint

So have done 5 races and eliminated 10 horses

If you don't like the first hint you can do by any method you want
