Vayer says Froome's supposed Ventoux data was leaked, not hacked

Files believed to show data from Chris Froome’s stage-winning ride on Mont Ventoux during the 2013 Tour de France were the result of a leak, rather than hacking, according to the man who made them public.

Team Sky announced on Monday they were taking legal action over a breach involving Froome’s files, and it is believed to be linked to the Ventoux data, which was published last week and later made into a video.

The data, posted by Antoine Vayer, a former trainer of the infamous Festina team, gives a breakdown of Froome’s speed, cadence, power output and heart rate over the course of the climb. The video, made by someone else – whose Twitter account was later removed along with the video – sets the figures against television footage, showing how the values fluctuated in real time, notably when Froome made his high-cadence attack on Alberto Contador.
