In order to ensure the best safety conditions, please note that you must be at least two to run the Marathon Day. Your state of health must allow you to do so. Think about following the instructions given to you by the organizers in your agency and respect the rules of road safety in urban areas.
Do not forget that the essential thing is to participate, so it is perfectly useless to want to exceed its limits at all costs.
Safety also requires appropriate equipment. Wear walking or running shoes and dress with comfortable clothes, adapted to climatic conditions. Finally, do not forget your bib!
