Mountain pass cycling milestones are signposts that provide cyclists with information about their current position with regard to the summit of the mountain pass. They always provide information for cyclists going uphill. Sometimes the signs are two-sided, thereby providing information also for cyclists going downhill. Mountain pass cycling milestones are particularly useful to cyclists that are not familiar with the climbs. In general, they allow cyclists to schedule breaks as well as to plan food and liquid uptake. They furthermore can serve as motivational landmarks.
