A proposal for Victor

The same race.
A clearer website.

This late-1990s-inspired concept preserves the original Tamalpa artwork, earthy palette, local photography, and the race director's voice. Classic type, underlined links, a practical runner sidebar, and restrained framing bring back the feel of an early trail-running website.

  1. A clearer first impression: the landscape, race basics, and registration path come first.
  2. Easier preparation: course, travel, and race-day details are grouped around runner needs.
  3. More room for the community: Victor's welcome, photography, and race history are part of the homepage.

Sponsor marks use grayscale in an open layout with separate prominence for presenting partners. Headlines are deliberately direct.

For discussion: confirm next-edition details, select high-resolution race photography, approve sponsor artwork, and invite Victor to supply his next welcome. This is a proposal, not the live race website.
