Mark Cavendish and Bradley Wiggins will compete together in Team Sky colours for the first time at the Tour de Romandie, which starts on Tuesday.
The pair will be among eight Team Sky riders at the 431-mile Swiss race.
Defending champion Cadel Evans of Australia, the 2011 Tour de France winner, is also competing.
No Briton has won the six-stage event, which begins in Lausanne and ends with a time trial in ski resort Crans-Montana on 29 April.
Cavendish joined Team Sky following the disbanding of the HTC Highroad team at the end of the 2011 season, but has yet to compete alongside Wiggins in his new colours.
The pair are joined by fellow Britons Chris Froome and Geraint Thomas in the Team Sky line-up.
