The pro-am Trois Etapes challenge cycle event will be televised on Channel 4 and British Eurosport in 2013.
The event takes place over July 26-29 in the Alps, and pits 14 charity teams against each other over four days of high-altitude riding.
Each of the 14 teams comprises seven riders and each is led by a professional rider, which this year includes 2008 Tour de France winner Carlos Sastre.
Prizes won by the teams are donated to the nominated charity. In 2012, a total of $1.7 million (just over £1 million) was raised for the charities involved.
Charities that have signed up to the 2013 event include the Anne Frank Trust, 1001 Fontaines, Shooting Star CHASE, EMpower, Prostate Cancer UK, Walking with the Wounded, Right to Play, World Bicycle Relief and the dZi Foundation.
A 30-minute highlights show produced by Cyclevox will be aired on Channel 4 and British Eurosport after the event.
