Enrique Llimona, from Huelva, is an amateur sportsman, “a normal person” as he assures. However, in 2016 he completed an impossible triathlon trial composed of: an 11.9 kilometres swimming competition, a run of 100 kilometres and a 525 kilometres bicycle race. It took him 41 hours and 45 minutes to complete it. This is the toughest sports challenge that no one has ever achieved. A documentary will tell the story of this ultraman athlete, and the funds it raises will go to the Spanish Association Against Cancer.
