"I received an email from him announcing his departure back to the United States and that he wouldn't participate, it's all that simple. That's it. It's not very complicated. It happened in a calm and normal way. It certainly is a big disappointment for him."
"It is true that we are sorry. Today we are turning the page. We have an event happening in six days and that's it. We are ready. We are building. There are athletes who are here to run the race. So that's it. It was a benefit. It was the cherry on top of the cake, but now we are back to business."
The organiser of next Sunday's Ironman France Nice triathlon has confirmed that seven-times Tour de France winner Lance Armstrong has pulled out of the race after being banned from competitive cycling.
"I received an email from him announcing his departure back to the United States and that he wouldn't participate, all that simply," Yves Cordier said in Nice on Monday.
Armstrong is facing charges by the U.S. Anti-Doping Agency (USADA) that he doped during his career. He had been training in the Nice area ahead of the Ironman race.
Armstrong's lawyers have demanded access to evidence gathered by USADA including test results and the names of witnesses who said they saw him use performance-enhancing drugs.
Armstrong could be stripped of the Tour titles he won from 1999 to 2005 and banned from cycling, though he retired from the sport last year.
USADA says that blood samples from 2009 and 2010 are consistent with performance-enhancing drug use and that more than 10 former Armstrong teammates and support personnel will testify they saw him use drugs or talk about using them.
USADA has said it will not release the names of witnesses at this stage to protect them against possible attempts at intimidation.
On Saturday four top U.S. cyclists - all former teammates of Armstrong - removed their names from consideration for spots on the Olympic team.
Levi Leipheimer, George Hincapie, Christian Vande Velde and David Zabriskie asked that they be taken out of the running for places on the road cycling team for the London Games, USA Cycling announced in a brief statement.
"USA Cycling will not speculate on the reasoning behind their requests and will not have further comment," the statement said.
