-Throughout the year, Ian Clermont trains continuously and assiduously to raise funds for sick children. His challenge: to run 105 km in a single day. As the months go by, he has to increase his pace and rhythm. His body is changing. Injuries loom. He has to reconcile work, training and family. "Le défi" is certainly not a racing film. It demystifies sporting performance at its most extreme, and empowers the individual to change his or her life. In an atmosphere tinged with humor, this documentary takes a human look at the paradoxes associated with surpassing oneself and giving of oneself.
