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.
MTN
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).
MTN/A/T
Advanced, technical, single track; ex. Lunch Loop
MTN/B
Easy single track, double track, fire roads. Mountain bike or cyclocross bike okay. Terrain varies with climbs and ascents, ”technical” mountain biking skills not required; ex. Uncompahgre Plateau
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.
