This is the only multi-day trip on the Ride Barcelona list and the biggest challenge on it. Over three days you ride 320 km of road in the Pyrenees and climb 7,400 m, which works out at roughly 107 km and 2,500 m of ascent a day. Everything around the riding is handled for you: a support van follows the group, hotel nights are arranged, and a mechanic travels with you to keep the bikes running.
The Pyrenees are what set it apart. Where the Barcelona big climb morning gives you one hard ascent before lunch, this camp strings long mountain passes together day after day, so the effort builds and tiredness is part of the plan. The Costa Brava coast road ride is also long, but it is sea-level riding with short climbs. Here the climbs are the point.
You start from Barcelona and spend the days in the mountains rather than on city roads. It suits strong riders who already train for climbing and want logistics taken off their hands.
