The most detailed and useful biikepacking planning aid for the Tour Divide Classic Northbound out there (TD Classic being from the US/CAN border to the US/ MEX border).
The Data Sheet has the most information. It gives the distance, elevation +/-, average grade, max grade, pavement sections, references ACA maps, bike shops, resupply options, key water sources, and has key notes between two Point of Interest (POI). Example: A and B, then B to C, and so on.
These Planning Aids cover the Tour Divide Classic route from the CAN/US to Antelope Wells, NM.
