Where do these data come from ?
Frédéric Portoleau, our "Watts expert" is doing all the power calculations. He started his times and watts measurements in 1988. The details of his work are available here.
Several chronos on the website have been measured by Vetooo, a finnish cycling fan. You can follow his activity on twitter here.
The threshold definition is done by Antoine Vayer.
"Not Normal ?", the magazine, has been created by Antoine Vayer, Stéphane Huby and Frédéric Portoleau.
