Because of the road closure on CA1, as stated in the rules, a rider may start at either end, proceed to the road closed sign, and take the required photo to complete the road requirement. OR, as an alternative, a rider may choose to ride CA70 between Oroville and Quincy.

There are Sixteen roads listed, but only FIFTEEN are required to be a Challenge finisher, the registrant can eliminate any ONE of the 16 roads offered.

*NOT required, but at the junction of NM35/NM15 take NM15 NORTH for 18 miles to the Gila Cliff Dwelling Nat Monument as a point of interest. Spur adds 36 miles
