Disgraced cyclist Lance Armstrong will return to competitive sport this weekend, entering a swimming event in Texas.
Armstrong, 41, has entered the Masters South Central Zone Swimming Championships, which are not subject to American or World Anti-Doping Agency codes or decisions.
Armstrong was stripped of his seven Tour de France titles last summer after he did not contest doping charges made against him.
The swimming event, to be held in his home town of Austin, Texas, will see Armstrong compete in the freestyle events at 500, 1000 and 1,650 yards.
He is competing with swimmers from his own age group.
Rob Butcher, of the event's organizing body, said no one had objected to Armstrong's involvement.
