Route: Bear Lake to Grand Lake, RMNP (CO)

This goes from Bear Lake on the East Side of RMNP and to Grand Lake on the West Side of the Park, via the Flattop Mountain Trail and the North Inlet Trail. The route goes up and over the Continental Divide via Flattop Mountain.  Since Bear Lake is higher, and the west side is more gradual, it makes sense to run from east to west for an FKT.
