Challenge:

Every year during the Tour de France, each team gets through over 5,000 bidons (drinks bottles). During races, riders throw these to the side of the road when they've finished with them, littering the surrounding countryside.

Opportunity:

As part of our campaign to be 'the greenest team on the Tour' we put our minds to how we could address this problem through harnessing our fans at The Tour.

Idea:

Team Sky Green Bottles: Recycle and win.

We took each of Team Sky's 5,000 Tour de France bottles, turned them green and printed a unique code on the top. We then launched a competition through Team Sky's facebook page: Pick up a bidon from the roadside, enter the unique code online and you'll to be entered into a daily draw to win money-can't-buy prizes such as signed Tour jerseys.

Results:

Live now - on Day 6 of the Tour de France, entries are flooding in - we'll report back on how we do.
