Although he did not start competing until his second year in the Children’s category, his love affair with cycling began when he was nine years old in his mother’s native country, France, where Valréas was born. But not because of the existence of any family member who competed or practiced it. In the nation that saw the birth of the Olympic Games, the World Cup, the European Football Cup and especially the Tour de France, young Marius watched the Tour of France on television with his grandfather. Those stages aroused so much interest in him that he began to wonder what the sport was really about. The working life of his parents, teachers, Tim and Laetitia, British him, French her, has led him to live in up to five countries. Marius was born in the Philippines. He then lived seven years in Indonesia, one in Mexico, two in Nicaragua and in Spain for three years. He is fluent in three languages: English, French and Spanish. In 2019 he competed with the José Manuel Moreno Academy, which allowed him to run in different parts of Spain. A mistake in transcribing a paper temporarily renamed him as Markus, a name that can still be found somewhere on the Internet without being updated.
