Global Marathon Routes is an independent reference site. There is no commercial race-entry service behind it — just an editorial team that keeps the course guides and the race data up to date.
The fastest route for corrections, data requests and general questions.
[email protected]Corrections and updates
Spotted a wrong record, a start line that has moved or a race date that has changed? Send the page address and the source you are looking at, and it goes to the top of the queue.
Data and citations
The numbers on this site are compiled from public sources. If you are citing the site, or need to know where a figure came from, ask and we will point you at the primary source.
Press and reuse
For anything else — using our maps, translating a guide, or working together on race data — write to the same address and explain what you have in mind.
What to expect
Corrections are usually reviewed within a few working days. We cannot help with race entries, ballot results or travel bookings: those are handled by the race organizers, and the official race site is the only place that can answer them.
Global Marathon Routes is not affiliated with, or an agent of, any race organizer or of the Abbott World Marathon Majors.
