In Italy you can do the famous Nove Colli Marathon in real life - 9 climbs in Marco Pantani's home area.
Here we have "Nove Colli Austria" - filmed at the end of winter which is quite nice still little bit of snow but spring waiting to break through too. In this second part you have to do 4 climbs and downhills - in the first part 5 climbs and downhills. If you do both rides you will have more than 2500m of climbing and downhills and about 90k in distance.
Perfect for interval training too.
