Half 20m circle from F to K?!!

[Murphy’s Gauntlet]

Hi all,
Just as the title says…
I’m doing BE102 at the weekend and the free walk is on a 20m circle starting at F and finishing at K …. So what part of the middle of the arena is where I’m aiming too after F?? Diagrams would be a bonus!! Thanks in advance

Well 10m further up from F (4m below X)

Dressage Diagrams sheets are really useful for this type of thing and aren't too expensive.
