Yesterday I took part of the fourth inter-state bike ride, requesting the construction of proper and safe cycling ways. Tens of Mexican bike-rider organizations were part of the organization, althought the effort is basically grouped under the Ciclopistas y Ciclovías Interestatales project - For further details on the route we took, you can look at the México-Pachuca road map, although it was not followed literally.
