About this concept

A contemporary alternative prepared for Victor by Erik. Original flame and race artwork retained; race information drawn from the official Headlands website.

The runner photograph is a licensed Unsplash placeholder by Lucas Canino, photographed outside Marin. It sets an editorial direction and does not depict this race.

Local landscape images come from the earlier concept using existing race-site photography. Final photo selections and photographer credits should be confirmed before replacing the official website.

The proposed August 17, 2027 date is unconfirmed. Route, logistics, results and sponsor references are from published prior-edition information.
