Chocobo sprint ability? or... Chocobo Racing?

[DoctorMog]

It is entirely possible that this is a race between the two people on chocoback and the effect happening in front of the rider on the left is a checkpoint.

Maybe it sits there stationary and players must run through it?

(Think old school arcade racing games)

But what can explain the running cactuar?

Maybe he is racing too?

Just a thought. It might not be the sprint ability.

Edit:
Found the video that shows the current sprint animation:

It looks nothing like the above image.

If indeed this is the chocobo sprint ability, why use a new animation?

Food for thought.
