Itineraries
Schedule plans for a 3 or 4 day ride
The right plan depends on weather, daylight, bikepacking load, fitness, and how much time you want in the towns along the route. A four-day schedule gives more room for mechanicals, cafe stops, and slow mountain sections.

Scheduling advice
Book flexible overnights where possible
Mountain weather can turn a short day into a long one. Tell accommodation hosts you are arriving by bike, ask about secure storage and drying space, and keep a late-arrival food option in reserve.
