R Randonneuring is long-distance (endurance) cycling over scenic and challenging terrain. Randonneur rides often leave early in the morning and require lights, go under most weather conditions, and typically are challenging all-day affairs with distance and speed determined by the participants. This includes the annual Brevet series of qualifying rides between 125 and 625 miles in length.
ATB These are rides for all-terrain or mountain bikes. The individual ride descriptions should be read for specific information regarding terrain (e.g., single-track, double-track, or gravel roads), distance, and equipment requirements (e.g., type of bike or tire width).
T Specialty rides for bikes with two or more cyclists. Tandem ride leaders often choose routes that are particularly well-suited to these types of bicycles, as they typically go much faster on down-hill and flat sections, and slower uphill, than single bikes.
