The first retro bike-a-thon in Mérida has brought together 50 cyclists on a 39-kilometre route riding bikes that are at least 30 years old, marking the 40th anniversary of the Cycling School in Mérida. The route passes by the San Lazaro Aqueduct, the Saint Eulalia Basilica, the Los Milagros Aqueduct and the Roman Proserpina Dam.
