Up to the date of writing this, he has had two relevant international competitions. Both of which took place in Ruhpolding (GER). He placed 13th in the first one and 9th in the second. More relevant is his placement in the Swiss Championships where, in the U16 category, he placed 8th, 6th and most recently 3rd on the 75m hills and, in the U20 category, he placed 10th on the 108m big hill. His currently best distance on the 75m hill is 74m, on the 117m it's 113m (371ft).
Marius' body is very lightly built at the age of 13 his weight was 43kg and he was 1 meter and 63cm tall. His muscle power is all in his legs and torso, he has pretty much no muscles in his arms, that's why many people call him a Leek which in German is often used for people who have just as little arm strength as he does.
