INTRO - The Challenge

Without cars, cities would definitely have a different structure.
Here you can find walking, running and biking distances in modern cities.

All distances refer to the city center and the following colours refer to the time needed from the city center to any point on these lines:



If you walk, run or bike often then I am sure that you have a rough perception of the distances in your city.

CHALLENGE YOURSELF:

Compose a map, (even though not accurate because you haven't been everywhere but its a matter of checking it out afterwords ;)
"This way you train your mind as well"

For me that is the motivation, "create and check", you have to prove its possible to others ;)

Send me your maps. I'll post them with a link signature to your profile or personal web-page!
