The sample is the same two files cut to five roads and 165 km. It opens on the Grossglockner and closes on the Silvretta, so you get both ends of what this book does in one download: a road that charges 46.50 EUR to drive it, and a road you should not drive at all. Four GPX files for five roads, for the reason on that page.
The index numbers are the book's own. The sample keeps them so you can see where the five sit among the 44.
Five of the 44, at full size, with four GPX tracks and the same key map of all 44 roads the paid book carries. Nothing is cut down except the number of roads.
The download opens as soon as you press the button; you do not have to wait for the confirmation email. I send the next edition's notes and nothing else, and every one carries an unsubscribe link. What happens to the address is in the privacy notice.
