Difficulty and terrain
Moderate. Flat profile, but 11.4 km of concentration on the line. Expect the distance, not the climb, to be the limiting factor.
Surface: Boardwalk asphalt, compact park gravel, and short cobblestone connectors in the Gothic core.
Safety: Early mornings on beachfront promenades are safer and less crowded than sunset tourist hours.
Best months: March to May and October to November for cooler temperatures and less humidity.
