Marathon Des Sables

Marathon Des Sables Medical Certificate

The stuff of legends, the Marathon Des Sables is quite the race! In fact, billed the “toughest race on earth.”

Whilst the certificates may look very simple, they require a thorough medical assessment. You must complete your medical assessment well before your event, so you have adequate time to complete the mandated tests and/or any additional tests which may be required if abnormalities are discovered during the assessment.

Will you definitely be able to sign me off as fit to participate?

Whilst we are able to sign most participants as fit to compete, if abnormalities are discovered, we may not be able to do so until additional tests are completed. This may include but is not exclusive to and echocardiogram or further cardiac tests.

You will still be liable for the full costs of the medical assessment, please note, you will be liable for the full cost of the medical even if you are not deemed fit to compete.
