The rating is called Pilgrim Pace and appears as a small PP badge beside the journey's title, always with its word. Easy means a relaxed physical pace: shorter walking periods, fewer stairs, shorter touring periods, frequent chances to sit or rest, and substantial free time. Moderate means regular walking and standing, which may include cobblestones, uneven surfaces, stairs, hills, longer periods on foot and moderately full touring days. Difficult means significant walking or prolonged standing, which may include substantial stairs, hills, elevation changes, challenging terrain, long days on foot or physically demanding pilgrimage activities.
The rating follows the itinerary, never the destination alone. Rome is a city, yet a Rome itinerary with security lines at St. Peter's, cobblestones, museum walking and coach drop-offs some distance from church doors is Moderate: about 2 to 4 miles (3 to 6 km) on the fuller days. Fátima and Lourdes, on level sanctuary ground with about 1 to 2 miles (2 to 3 km) a day, is Easy. Where an itinerary does not yet have enough detail to state a distance or a day length, the page says so and marks the item for confirmation rather than guessing.
Good to know before you go: Pilgrim Pace is separate from Pilgrim's Time, the unscheduled or lightly scheduled time built into each day for prayer, rest, a café, confession or conversation. One tells you how demanding the journey is, the other how much room it leaves you. And the rating is a planning guide, not a guarantee. Actual distances, terrain, weather, crowds, transport access and accessibility can vary on the day, so if a particular limit matters to you, such as stairs, long standing or a wheelchair, ask about that specific point before you commit.
