Preparation
The organiser advises everyone not to make any strenuous efforts for which they are not physically prepared. Make wise choices regarding the distance you want to cover and/or the pace you want to impose on your body. If you want to do sports with a high performance and intensity, it is best to have an annual check-up by a (sports) doctor.
The submission of medical certificates is not mandatory. It is up to the sportsman himself to decide how to deal with the information he receives during a medical examination. The organiser does not bear any responsibility in this respect.
