Step-by-step guide to design and build your own mini obstacle course (obby)
Step 1
Gather all the materials listed and bring them to the play area.

Clear a safe open space on the floor so you have room to build and run the course.
Step 3
Use a marker to sketch a simple course layout on a flat piece of cardboard.
Step 4
Cut and fold cardboard to make one obstacle such as a ramp tunnel or bridge.
Step 5
Use tape to secure the cardboard pieces so the obstacle is sturdy.

Decorate each obstacle with bright marker designs.
Step 8
Give each obstacle a silly name and write the name on it with a marker.
Step 9
Mark a clear start and finish on the floor using tape or a marker.
Step 10

Step 11
Use a timer to do a fast timed trial and write down your time.
Step 12
Change one thing in the course to try to make your time faster.
Step 13
Run another timed trial and write down the new time.

Help!?
What can we use if we don't have large cardboard, a marker, or a timer?
Use flattened cereal boxes or folded poster board to cut and fold into a ramp or tunnel, a pencil or crayon instead of a marker, and your phone's built-in timer for the timed trials.
What should we do if an obstacle keeps collapsing or moving during the practice run?
If a cardboard obstacle wobbles or cushions slide, reinforce folds and seams with extra tape, add a folded cardboard brace or heavy book underneath the ramp, and put a non-slip mat or rug under cushions so the obstacle stays sturdy for the timed trial.
How can I adapt the obby for younger toddlers or older kids?
For toddlers, simplify by using only cushion stepping-stones and a low folded cardboard ramp with adult help for cutting and supervision, while older kids can add higher ramps, tighter time goals, and rules like 'no touching cushions' to increase difficulty.
What are fun ways to extend or personalize our obby after the first trials?
Add a theme and bright decorations to each obstacle, write silly names on cardboard signs, create small checkpoint tasks to earn points, attach LED string lights for flair, and keep a chart of best times and which single course change improved performance most to share on DIY.org.
