A lumpy Italian 600 km randonnee was promoted before the start of the Mille Miglia and it might interest some forum folk next year. Dipping into Italy, France and Switzerland, there is over 10,000 m of elevation gain including the Col du Petit St Bernard (2188 m). There are two options, an ACP-homologated 40 hr limit and the Super Randonnee 50 hr limit. I'm not sure I'd rely on this as my PBP qualifier.
