This is a full day on a road bike along the Costa Brava, covering 118 km with about 1,650 m of climbing. The route follows the cliff road between coves, dropping down to the water and climbing back up again, and stops for a seafood lunch in the middle of the day.
The climbing comes in many short and medium pitches rather than one big mountain, so the effort is steady and cumulative. It is rated hard because of the distance and the hours in the saddle, not because of any single ramp.
Within the Ride Palma range, this is the scenic endurance day. It is the longest single-day ride on the site, longer than the Palma big climb morning (62 km) and the gravel days, and it trades a headline climb for coastline and a proper sit-down lunch. If you want a summit test, look at the big climb morning instead. If you want distance with views, this is the one.
