When poking into twitter earlier today I saw a post from Matt Cutts who had linked to an interesting TechCrunch article.
It seems that Kristin Armstrong used a GPS and Google Earth to help her train for her Gold Medal performance in Beijing last month.
During a trial in December of ’07, Armstrong brought along her husband’s GPS to capture elevation along the cycling route. She then took this information home and after exporting the GPS data into Google Earth was able to plot out a similar route in her home town of Boise. Having a close match to the course in terms of elevation and distance, gave Armstrong the ideal method of training, which, in the end allowed her to grasp that coveted Olympic gold medal!
