Lance Armstrong (Team RadioShack) and Alberto Contador (Team Astana) will compete in the 2010 Criterium International, their first race together since the Tour de France last year.

Contador announced Tuesday that he had changed his plans and will compete in the March 27-28 race in Corsica instead of events in Catalonia and the Basque country. The defending Tour de France champion won the Paris-Nice event on Sunday.

Contador and Armstrong were uneasy teammates at Astana last season. Armstrong finished third in the Tour de France, his first since winning seven straight from 1999 to 2005. He left the Astana team and now races for Team RadioShack.
