If you’re preparing for a marathon, there’s more to organise than just training and travel. Many events require a marathon medical certificate — a document signed by a doctor confirming that you’re medically fit to take part.

This guide explains what a marathon medical certificate is, why organisers ask for one, and how to get yours online quickly, without unnecessary delays.

What is a Marathon Medical Certificate?

A marathon medical certificate is a document signed by a licensed doctor confirming that you are medically fit to take part in a marathon and have no health conditions that would make participation unsafe.

Event organisers use this certificate to verify that runners meet the medical requirements for endurance events and to reduce the risk of serious health incidents during the race.

For a broader overview of sports medical certificates and how they apply to different events, see our Complete Guide to Sports Medical Certificates.

Why Is a Marathon Medical Certificate Needed?

Some may view a fit-to-run medical certificate as just another box to tick, but it’s actually an essential screening tool designed to safeguard your health and ensure a smooth race day for everyone involved. Here’s why these certificates matter:

Protecting Your Wellbeing

Running a marathon is no small feat — it’s a grueling physical challenge that pushes your body to the limit. Not everyone’s health can safely handle that level of exertion. A medical certificate ensures that common issues, such as heart or lung conditions, have been screened before you hit the starting line.

Countries like France and Italy have stringent laws for running events to ensure the health and safety of participants. By requiring medical certificates, organisers comply with these rules and protect themselves from legal issues in the event of a medical emergency.

Hosting a marathon involves significant insurance coverage, and a key condition for that coverage is ensuring all participants have valid medical certificates. Additionally, if runners have personal insurance, not having the right certificate could lead to denied claims.

In short, a medical certificate protects both runners and event organisers — making it a win-win for everyone involved!

Marathon Medical Certificate Requirements in France and Italy

If you’re gearing up for a marathon in France or Italy, you’ll need to ensure your medical certificate meets their specific requirements. Here’s what to keep in mind:

Check the date

Medical certificates are typically valid for 12 months, reflecting the importance of reassessing your health regularly. Make sure your certificate is up to date before race day.

Event-specific templates

Many marathons in France, Italy, and other parts of Europe require you to use their own medical certificate template. Popular events like the UTMB Series, Marathon des Sables, Florence Half Marathon, Transgrancanaria and Tor des Géants often provide templates that must be signed by a doctor. 

Special Wording Requirements

French and Italian race organisers can be very particular about the wording on your certificate. Most events require it to state that you have no contraindications to participating in competitive running events or a similar phrase. 

Recent Rule Changes

From 2024 onwards, some French running events like the Paris Marathon and Mont Blanc Marathon have replaced the medical certificate with a Health Prevention Course.
