Dressage test :(?

Question

i dont know what they mean when they say

A...........circle left 20 metres diameter with transition to working canter when crossing centre line

does that mean at A i canter or midway through circle? im so confused!

if you know ill be so happy thanks!!

Answer 1

Centre line is A through C. So you begin your circle at A, and when you are halfway through the circle (which would be centre line) I presume that is when you would start your canter.

Answer 2

what and where is this test from? I have never seen this movement before

Answer 3

It means you canter midway through the circle. Start your circle at the trot and once you reach the center line pick up your canter. Then complete the circle at the canter.
