Why does walking 500 meters feel like 2 kilometers?

The short answer

No straight sightlines. Every turn resets your mental map. Add heat, crowds, uneven ground, and constant sensory input — perceived distance stretches.

The shortest route between two points involves fifteen or twenty turns, each requiring a decision. Decision fatigue adds cognitive load that your brain interprets as distance.

Your pace drops from a European-sidewalk average of 5 km/h to a medina average of about 2 km/h. Five hundred metres at 2 km/h takes fifteen minutes. Your body expected six.

Your host's "five minutes" is their five minutes — they know the route, skip the decisions, walk at medina pace without the cognitive overhead.
