CYCLING-GERMANY-ULLRICH

German cyclist Jan Ullrich, 1997 Tour de France winner, gives a press conference to announce his retirement from cycling, 26 February 2007 in the northern town of Hamburg. 33-year-old Ullrich was one of dozens of cyclists implicated in an alleged doping network in Spain last year, which forced him out of competing in last year's Tour de France.
