San Silvestre Santurtzi is a New Year's Eve run held in Santurtzi, a port town in Bizkaia, Spain's Basque Country. The race distance is approximately 6.8 km, though some sources list it as 6 km, placing it in the short road-race category rather than a 10K.
Participants begin and end at Parque de Santurtzi, near the pergola. This event is part of the broader Bizkaia running schedule and is intended for recreational runners, local club members, and individuals seeking a brief race before evening festivities.
