It is a rare and somewhat exceptional event: two sons, Sebastien is an elite trail-runner and his brother Sylvain, a semi-pro trail- runner, introduce their sixty-year-old father Pascal to mountain running. And not just any trail : ultra-trail! Each of them faces their own personal test on UTMB® 2018: the 120 km-TDS® for Sylvain, the 170 km-UTMB® for Sébastien and Pascal runs his first ever 100km joining the CCC®. Not another story about racing, a family affair.
