Mesa Marathon
Mesa, AZ · Feb 13, 2027
Forgiving course · Some friction
Every race here was checked by a human.
Directories scrape every race they can find and let you sort by date. That is a different product. A race-day date that is quietly a year stale, or an elevation figure copied from a listing nobody checked, doesn't just mislead you — it invalidates every number computed from it, which here is all of them.
So the catalog is deliberately small and audited. 37 of 40 verified at the official source; 3 carry a projected date because the organiser hasn't announced one yet, and say so on their page. It grows when a race has been verified, not when one is found.
