I will be wearing Green and it has nothing to do with Sprint.

Yellow: The maillot jaune,  The yellow jersey is the well know shirt of the tour de France.  It is warn by the overall leader of the race so far.  The yellow jersey is awarded at the end of each of the 20 race days.  Each day the times are added to the total from the previous days and the fastest overall wears the yellow the next day.

Green: Vert, this is the sprinters jersey, the amount of sprint points depends on the days course, a flat course produces more points than the hills, some parts of the course have minis-sprints that are worth sprint points.  I and the other volunteers on the Grand Depart will also be wearing Green, although tee shirts and jackets not cycling jerseys,  something to do with the sponsorship from a large all know supermarket.

The white with red spots, is the King of the Mountains, on the women’s Tour of course it is the Queen,  but as yet no women compete in the Tour de France,  on this race there will only be Kings.  Points awarded for hills or mountains.

White:  This is the fastest of the young riders, under 25. Certainly the ones to watch for the future.

There are other shirts too, mostly team colours, really this is a team race. Each team will have both sprinters and climbers, and some of the riders support their teams elite by protecting them.  The Team prize is based on the three fastest riders of the team.

On the flat roads, like those here in the UK there will be only seconds between the pack, known as the peloton.  The route is tough, covering over 2,250 miles with some very steep mountains. The Alps - where you will see the best separate from the peloton.    It would take about 40 hours to drive the route by car, and even longer for the caravan of support wagons and floats to cover the course.

I'll be supporting the team sponsored by Sky, their team shirts are black with a sky blue stripe, although of course I hope that they will be wearing the coloured shirts after the first day.
