Sure thing, love a good challenge. Think about turning the course into a puzzle‑labyrinth that shifts as you run—like the walls move when you solve a riddle, or a secret door opens only after you hit a specific rhythm in your jumps. That way the brain has to keep up with the body, and every step feels like a fresh mystery. Try adding a timer that you can only reset by finding a hidden key hidden in a place you’d normally skip. Keeps the adrenaline and the mind racing in sync.
