Add a marker location by pressing the [+ Route] button of the marker popup window.
The first location you add is considered to be the start of your journey. If you click ‘Calculate Fastest Roundtrip’, it will also be the end of your trip. If you click ‘Calculate Fastest A-Z Trip’, the last location (the one with the highest number), will be the final destination.
If more than 15 locations are specified, you are not guaranteed to get the optimal solution, but the solution is likely to be close to the best possible.
Up to 100 locations are accepted. You can re-arrange stops after the route is computed. To do this, drag or delete locations into the ‘Edit Route’ section.
