Vintage Roadbike

Randonneuring (also known as Audax in the UK, Australia and Brazil) is a long-distance cycling sport with its origins in audax cycling. In randonneuring, riders attempt courses of 200 km or more, passing through predetermined "controls" (checkpoints) every few tens of kilometres. Riders aim to complete the course within specified time limits, and receive equal recognition regardless of their finishing order. Riders may travel in groups or alone as they wish, and are expected to be self-sufficient between controls. (Source: Wikipedia)
