So the optical detetectors should be able to "cover" a row of holes. And by connecting the two yellow sensors and the two blue sensors I will get three signals coming from each lane.
Shown are two yellow sensors, two blue sensors, and one red sensor. That's five sensors (signals). If it gets critical you could wire-or the yellows and blues together to get three signals.

A bicycle chain might work for moving the horses. It's cheap, widely available, and easily strong enough. And, I think with some careful design, you could count links to know how far a horse has been moved. This would negate the need for a stepper motor.

You may be able to get away with only one motor if you could mount a shaft the width of all the lanes and attach a clutch for each lane.

Hey Ya'll,
   Has anyone completed this project? I'm interested in tackling this soon.

Thanks

Shinguki, i got mine working with two lanes. Let me know if you are still interested.

Does anyone know where I can buy the racehorses with their riders?

You might find them sold as arcade supplies.

Your sketch can sense ongoing process events in time.

I wonder though if instead of horse race it could be a train race? 

If you think "not exciting" then maybe have a look at the early steam engines in the time of "The Rocket".

As electric trains the movement should be easy to implement.

And it doesn't have to be train bodies either.

Hi.

I completed this project with 14 lanes, and I added 2 digits giant seven segment display.
