This is the one trip on Ride Palma that leaves the island: three days of road riding in the Pyrenees, covering 320 km and 7,400 m of climbing. That works out at roughly 107 km and about 2,500 m of ascent each day, so the ride is built around long mountain passes rather than rolling terrain.
The logistics are handled for you. A support van follows the group, a mechanic is on hand for the bike, and you sleep in a hotel each night. You carry little more than what you need for the day, and you can concentrate on pacing the climbs.
Compared with the Palma big climb morning, which is one sharp ascent and a free afternoon, this is a full block of mountain riding, day after day. It is also a very different proposition from the Costa Brava coast road ride, where the climbing is rolling and the day ends at a lunch stop. Here the effort accumulates, and recovery between days matters as much as fitness on the first morning.
