What is the yellow one for?

Lance wore two yellow bands when he won the 2004 Tour de France

The yellow Livestrong wristband was set up by American cyclist Lance Armstrong to increase awareness of cancer.

The cyclist was diagnosed with testicular cancer that had spread to his lungs and brain when he was 25.

After chemotherapy he went on to win the 1999 Tour de France and has won it six years in a row.

Profits from the sales of the yellow bands go to the Lance Armstrong Foundation that helps young people with cancer and their families cope with the illness.
