Google Earth is praised by Kristin Armstrong, who won the Olympic gold medal for cycling. During her visit in December 2007 in China, she took with her husband, the GPS unit to determine the height profiles along the route. You use this data to find a similar route at home and train. In a commentary on the Google Lat-Long blog She writes:
After returning home in Boise, Idaho, I exported the GPS data in multiple formats, and would on Google Earth find anything. There I was, away from the comfort of my home and half a world, make a similar route in Boise identified to train under realistic conditions. This possibility, together with the height profile has proven invaluable in preparation for my Gold Medal race.
Google proves once again that information is a competitive advantage. training company
