Worldwide Half Marathon Calendar � Manually Vetted Races

"Discover the most accurate and trusted worldwide half marathon calendar. Every race is manually vetted and approved by experienced runners." That is how Worldwide Half Marathon Calendar � Manually Vetted Races introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.4 out of 10.

On the page itself the strengths are clear: a clearly stated business identity. It is passable on a workable page structure, a few credibility markers, basic crawler access and partial sitemap and link coverage. What holds it back is structured data describing the business.

Away from its own site, other sites link to it. Beyond that, the domain does not yet read as established, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on, nobody is discussing it where AI engines look and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). The site links to no social profiles, so there is nothing tying the brand to a wider presence.
