In interval training for 80/90 eventing, what should you do if the event level is higher?

• A. Keep time unchanged
• B. Decrease time
• C. Increase time
• D. Remove rest

Answer: (C)

When you’re aiming for a higher level in interval training for 80/90 eventing, you want to push the horse a bit longer during the active work phase. Extending the time of each work interval increases the sustained effort the horse must maintain, which builds endurance and helps the horse handle the longer, more demanding courses. The recovery periods aren’t removed; they give the horse a chance to recover before the next burst, which is essential for safe, effective training.

Keeping the interval time the same wouldn’t provide enough stimulus to adapt to the tougher level. Shortening the work interval would underprepare the horse by not sufficiently challenging the cardiovascular and muscular systems. Removing rest would push the horse into continuous work, increasing fatigue and risk of injury.
