Data correction	Wrong date, location, distance, registration status, map, or official link.	Race page, official source link, and the exact field that should change.
Submit a marathon	Organizer review booking questions before the paid submission flow is complete. This is not runner race registration.	Race name, official website, race date, city, country, and organizer contact.
Billing or cancellation support	Existing paid membership, organizer review payment, refund, or cancellation questions.	Account email, payment reference if available, and what you need changed.
General inquiry	Anything that does not fit the other request types.	A short description and any relevant Sunday Marathon page link.

For race data corrections, include the race page, the official source link, and the exact date, location, distance, registration, or organizer detail that should change.

Race correction checklist

Corrections go into the correction review queue so Sunday Marathon can compare the request against official evidence before changing a public race page.

Race: Galaxy Vladivostok Marathon
Race page: https://sundaymarathon.com/marathon/galaxy-vladivostok-marathon-2026

Include	Why it matters
Official source link	The organizer website, registration page, or official announcement is the fastest way to verify the correction.
Exact field	Name the date, location, distance, registration status, map, organizer, price, or source detail that should change.
Replacement value	Tell us the exact value the public listing should show after verification.

Accepted fixes update the public listing after verification. If the evidence is incomplete, the page stays conservative instead of guessing.
