Six times Tour de France winner Lance Armstrong has announced he will retire from cycling after competing in the event for the last time in July.
The US cyclist has decided to end his 14 year career with the big race: "Le Tour will be my last professional race - win or lose," he told reporters.
The sportsman famously beat cancer before winning his first Tour in 1999.
He started the recent wrist band craze when he launched the yellow Live Strong bands to raise cancer awareness.
In 1996 Armstrong was only given a 50% chance of survival after doctors discovered he had brain, lung and testicular cancer.
But he recovered from the disease and went on to break world records.
Armstrong admitted that he would find it difficult to stay away from cycling, but said he had made up his mind about quitting the sport.
"I'll definitely have the itch to return but the decision is final - I'm 100% committed," he said.
It's thought that after retiring Armstrong plans to spend more time with his children and raising awareness and funds for fighting cancer.
