The Running Hackathon
Barcelona's first. Teams ran through Poblenou to the beach building with voice and AI coding tools, then demoed on the roof.
Barcelona · September 21-24, 2026
Forty-two sessions,all free.
Masterclasses, clinics, hands-on builds and a few things nobody expected on an AI programme, hosted by the Claude ambassadors in one building in Poblenou. Here they are, by theme: what was taught, who taught it, and what people said walking out of the room.
