MadridCycleTrack initiative essentially collects GPS routes from cyclists. The collection of GPS routes has been temporarily out of service. However, in order to facilitate volunteer participation temporaly, it is also possible to draw your route through this user-friendly online application. Once you finish, a pop-up window will ask you to introduce information about your route, which will be considered with research purposes.Http iframes are not shown in https pages in many major browsers.
