Most of Brajkovic’s peak power values for the entire Tour were set on today’s stage. These include:
The stage finished on a short uphill where Brajkovic maxed out at 807 W and averaged 566 W for one minute. He also had a small crash near 79km but managed to avoid the crash near the finish line. It looks as if he may have changed bikes for about 13 minutes before he got back onto his original bike. Peak 5-minute power (398 W) was set on the second to last climb. The final two hours was raced at 320 normalized power!
TrainingPeaks' Training Stress Score (TSS) system allows any endurance athlete the ability to quantify their workouts based on their relative intensity, duration and frequency of workouts.
Normalized power provides a better measure of the true physiological demands of a given training session - in essence, it is an estimate of the power that you could have maintained for the same physiological "cost" if your power output had been perfectly constant (e.g., as on a stationary cycle ergometer), rather than variable.
Intensity Factor provides a valid and convenient way of comparing the relative intensity of a training session or race either within or between riders, taking into account changes or differences in threshold power.
Watts per kilogram is the standard measurement of a rider's "power to weight ratio" and represents a rider's average power output over a period of time, divided by the rider's body weight. w/kg equalizes power output between riders of various sizes and, all else being equal, increasing power (watts) or decreasing weight (kg) will make a rider faster.
