Set up 2 fences 36 feet apart (two normal sitting trot strides).
Approach at the working sitting trot. After the first fence, the horse should land and take exactly 2 strides to the second.
Keep your leg on between the fences. Look up at the second fence, not down.
If the horse adds a third stride, approach with more impulsion next time.
If the horse gets to the second fence in one big stride, collect on the approach.
Practice until 2 strides feels automatic.
Common Mistakes to Avoid
Panicking between the fences and pulling the horse back.
Not enough impulsion, causing a chip-in third stride.
The horse jumping flat over the first fence, landing too far into the line.
The rider interfering with the horse's natural stride between fences.
Variations & Progressions
Try 35 feet for a steady 2 strides and 37 feet for a forward 2 strides.
Add a third fence at 36 feet for a 2-stride to 2-stride combination.
Ride the 2-stride in 3 strides (collected) for advanced adjustability.
Tip: Two strides is the most common combination distance. If you can ride it cleanly every time, you can handle anything the course designer throws at you.
