This is the gentlest full day on the Ride Barcelona list: about 40 km on an old railway path that runs from Barcelona towards the coast, with only around 180 m of climbing in total. The surface is flat and traffic-free, so there are no junctions to watch and no hills to dread. You ride on a touring bike at your own pace, which suits mixed groups where one person likes to stop and another likes to keep moving.
The day is built around the rhythm of a long, easy ride rather than a target. You leave the city, settle onto the greenway, and let the distance build slowly until the sea comes into view. There is time to stop for coffee, a swim stop if the weather allows, and a relaxed meal before heading back.
Compared with the other tours on the site, this one asks the least of you. It has none of the sustained climbing of the Barcelona big climb morning, none of the technical choices of the gravel days, and none of the short, sharp climbs between coves on the Costa Brava road ride. It is a full day outdoors that nearly anyone who can ride a bike can enjoy.
