After you have created the starting point, create your first waypoint.
To make it easy for users to follow the route, make as clear as possible directions as to which way the walker or cyclist should go at the route point.
Take a look at the example route for this and it will become clear.
The walker or cyclist therefore follows the route from route point 1 to the last route point.
This can be an end point of the route, but can also end at the starting point.
