What it is

An obstacle course challenge inspired by TV ninja shows. Children train like ninjas, then race through a course in the garden. Finish with a belt ceremony so every child wins.

Plan ahead

  • Two weeks before: buy or borrow a ninja line or slackline kit, cones, hoops and a balance beam.
  • The day before: build and test the course. Make sure every obstacle is low and safe.

The obstacle course

  1. Agility ladder: quick feet through each square.
  2. Hoop jumps: jump into each hoop.
  3. Balance beam: a plank on the grass.
  4. Tunnel crawl.
  5. Ninja line: swing along the hanging rings (low enough for feet to touch).
  6. Bell tap: jump up and ring a bell to finish.

Ninja tests

  • Sleeping master: an adult sits blindfolded; ninjas sneak up to take a treat. If the master hears and points, they go back.
  • Laser maze: string or crepe paper criss-crossing a hallway; get through without touching.

Food and drink

  • Sushi-style sandwich rolls
  • “Throwing stars” (star-shaped cheese)
  • Water and juice
  • A black-belt cake

Tips

  • One adult at the ninja line at all times.
  • Give everyone a “personal best” so it isn’t just about the fastest.

On the day

  1. Dojo welcome (10 min): ninja headbands and ninja names.
  2. Ninja training (20 min): balance, jumping and crawling drills.
  3. Obstacle course (30 min): timed runs with a leaderboard.
  4. Ninja fuel (20 min): food and drink.
  5. Ninja tests (20 min): sneak past the sleeping master, and the laser maze.
  6. Black belt ceremony (10 min): every ninja earns their belt.
