Italy - GranGarda (Gravel)

"From https://grangarda.com/gravel/ "Mixed terrain loop with a considerable elevation gain that goes by dismissed military roads, fast double tracks, some technical singletrack and a few hike-a-bike. Mostly stays in a rural and alpine landscape, passing by small towns and villages. Some mountain passes may be closed for the remaining snow until the end of April. Includes some remote area and needs some planning in stages and resupplies. Plenty of lodging options and camping areas". "
