During the 2010 Tour de France in July, the Lance Armstrong Foundation and Nike worked together to print inspirational messages on the road along the route. This was done using the Livestrong/Nike Chalkbot.
The messages were printed each morning before the stage was to start and they were washed off the road after the stage was completed. The messages were printed using a soy-based material, which was very environmentally friendly.
In the early stages of the race I submitted a small message through the Livestrong website. I imagine that there was a huge response and I have to wonder how many people thought their messages were going to be printed.
On August 10, 2010, 16 days after the race was over I received an e-mail from Nike stating that my message had indeed been printed during the race. The GPS coordinates for my message are: 0.067164,42.950947 and it was printed on July 19, 2010. According to Find Latitude and Longitude website, this is Bageneres-de-Bigorre, France. This would have during stage 15 which ran from Pamiers to Bagnères-de-Luchon.
