Desc: Le Guidon dans la Tête: Directed by Timothee Catherine. With Jean-Luc Perez. Alone on his bike, Jean-Luc Perez is about to cross France through a 2600 kilometers track. Jean-Luc's goal is to beat the record in less than five days, which implies never stopping or sleeping. What kind of fascination pushes a 48-year-old man, family man and teacher at the famous Louis le Grand high school in Paris, to ride through entire countries, restless and sleepless? Is it existential for a physics and chemistry teacher to live the contraction of space and time in his flesh and bones?
