Well then, assuming the crodlu can go about as fast as a Deinonychus (which is about 40 m.p.h. if i am not mistaken), then i would say ‘yes’! You could go up to the crodlu’s maximum speed limit. Making the chariots Athas’ fastest vehicles! Woopee!
Edit: Still have to take in to account terrain and wind speed though. Would have to have a relatively smooth hard surface with at least moderate wind speeds.
P.S. That gives me an idea for Draxan sports! Sailed chariot racing! It could be like a yearly big event, it could be a short race in an arena or a long race that takes many days across the wilderness! With the only rule outside the city being ‘Don’t lose’! I see many adventure plot hooks there!
