The tour type is a dropdown; a bike tour picks its profile, routes for it, says when a point lies off every way, and shows what it runs on: surfaces, kinds of way and, for a mountain bike, the trail grades, each pointed at on the map. A type's own map (OpenHikingMap for a hike, CyclOSM for a bike tour) is offered while a tour of that type is open, with an admin switch each. From the planned cards: a hike avoids steep climbs, steps or ferries, nothing else; a saved tour can be shared where the platform takes GPX files; and the tours rail adds a tour from one menu: plan new, import GPX, or take one over from another trip.
