This is a tough century on some of the most popular Alta Alpina territory roads.
You can choose a start window between 7:00am and 9:15am. The course is open until 8:30pm for a total of 13.5 hours. Each rest stop has opening and closing times that must be respected and volunteers will strictly enforce cut-off times intended to keep everyone safe. (If you need a later start time, substitute for a different first pass.)
