David Millar will resume racing on 5 May after his Cofidis team announced the end of their self-imposed three-week exile from competition.
The decision to stop racing came after doping accusations made by a sacked rider and Millar had to miss riding in the team pursuit at the World Cup.
But Millar could still compete in the event at the Olympics as well as the road time-trial.
Cofidis will return for Wednesday's start of the Four Days of Dunkirk race.
"This exceptional break allowed the sponsor time to reflect on the team's future and its investment in the sport," Cofidis announced in a statement.
During their absence Cofidis lost Spain's road race world champion Igor Astarlow, who cut short his contract to join the Italian set-up Lampre in an amicable separation.
The claims of doping levelled by Philippe Gaumont have been dismissed as wild by Millar and as lies by Cofidis' managers Alain Deloeuil and Alain Bondue.
The French police have nevertheless launched an inquiry with eight people under investigation.
