around / on the track

I'd use either "on" or "around".

Thanks. But, my teacher said that we can't use "on the track", must use "around" why?

Can I say,

(a) The horse is galloping to the (race) track.
(b) The horse is galloping in / on the horse track.

You can use both, different meanings:

on: on the surface of the track
around: shows the trajectory of movement (oval, circle)

Can I say,

(a) The horse is galloping as fast as lightning
round the track.

Yes

Can I say,
(A) The rider is galloping with his horse.
(b) The rider is galloping away with his horse.

Use "on his horse" not "with his horse," which gives the unlikely but amusing image of the person running alongside his horse.

So, what is the correct answer?

Hi,

Can I say,
(a) The horse is galloping on the (race) track.
(b) The horse is galloping around / at the track.

You can say all these things, but the focus is different.

(a) The horse is galloping on the (race) track. Focuses on the surface involved. eg The horse is not on the road, not on the sidewalk.

(b)
