The BIG TEN is a combination of the ten best single track trails that reach 10,000' or higher in New Mexico. We do the trip over ten days due to the high altitude and technical nature of these trails. The tour takes place in the Santa Fe Nat. Forest, each trail is a full day ride of an average of 15 miles and elevation gain of 5,000' or more. This trip is for those who want to go all out! You must have prior mountain biking experience on single track and be in great physical shape.
