Cross country is running over uneven ground. Uphills, downhills, roots, mud. Form has to adjust without breaking down. This drill puts the runner on real terrain and teaches them to keep the form even when the ground changes.

What you need: A trail or grass course with mixed terrain (uphill, downhill, flat). Running shoes appropriate for trail.

Setup: Runner at the start of a 1-mile loop.

How to run it:

  1. Cue: arms forward and back, knees up, eyes 10 feet ahead.
  2. Run at a comfortable pace. Mile time should be 1-2 minutes slower than the runner’s track mile.
  3. Uphill: lean slightly forward, shorten the stride, keep the arms moving.
  4. Downhill: lean slightly back, lengthen the stride, control the speed (don’t let gravity take over).
  5. Flat: full stride, full effort.

What to watch: Form breakdown on hills. Most kids hunch forward going uphill (good) but stay hunched after. Reset posture at the top.

If they’re struggling: Shorter loop. Or run a flat loop first, then add hills.

If they’ve got it: Add a tempo segment. Run the middle quarter mile at race pace, then ease back.
