The Queen of Classics, known to be dangerous, takes place this Sunday in a tense context surrounding questions about the safety of runners. Paris-Roubaix Challenge is this amateur cycle touring race which offers its participants the chance to measure themselves against the real route of the pros.

Three distances are offered (170 km, 145 km and 70 km) With one thing in common: the cobbled sectors, just like the finish at the Roubaix Vélodrome, are identical to those of the biggest French one-day race.
