The jersey of River Sestao, signed by several runners, attests to the fruitful career of the left bank of Biscay. Sestao, a working-class municipality, lit up many cyclists through the River club, originally supported by the company Altos Hornos. The signatures on the garment correspond to illustrious names from his school (such as a young Julián Gorospe or other local professionals), which would symbolize the cohesion of the club. The black-green shirt displayed embodies that edel characteristic of the mining area. Celebrating the River Sestao is recognizing the contribution of a modest club that, with unity and determination, raised many kids from the streets of Sestao to the main national events.
