To commemorate the 100th anniversary of Tour founder Henri Desgrange's ride over the Galibier in the French Alps, this year the riders will twice climb the most-visited pass in the race's history, reports the BBC.
There are two main changes this year that will alter the way points are distributed:
- In an effort to involve sprinters in more than just the daily finish, 20 green jersey points -- up from six last year -- will be on offer in a single intermediate sprint each day and points will also be awarded to the next 14 finishers.
- The polka dot jersey, worn by the best climber, will see double points being awarded only for crossing finishing lines at the summit of category two and harder climbs.
The defending champion Alberto Contador of Spain is a strong pre-Tour favourite along with Luxembourg's Andy Schleck -- find all the Tour de France 2011 teams listed here.
The appearance of Contador is marked with controversy as the rider awaits the outcome of an appeal against a provisional ban; after failing a clenbuterol test.
