Madrid to Barcelona is an ultracycling event. The third edition will take place on May 30, 2025. Participants will have to complete the 700Km and +7000m following the GPS track that we have created for the event that will connect Madrid with Barcelona. The event will be unsuported. Adventure, self-sufficiency, nature and cycling will be the factors that will accompany you during the 50 hours available to complete the entire route.
