Blue Heron Loop

Ambitious A real undertaking. Demanding on a couple of fronts, like rough surfaces plus steady climbing, or a long stretch on busier roads.

Difficulty Our overall read of how demanding a route is. We score surface roughness, climbing, singletrack, and how far it runs from services. The route publisher's own rating, a lot of busy road riding, or sheer scale can push the tier up, never down.
