E-Doper

 

Have you ever wondered exactly how much faster you would be over a given route if you were 10% stronger? How about twice as strong? Or even half as strong? With BikeMetrix E-Doper, you can now create doped rides based on actual ride conditions for a particular day and answer these questions with hard data. You can then export your doped rides as a TCX or GPX for further analysis in your favourite analysis app to figure out where you need to improve to hit the power targets necessary in the doped ride, or where you are gaining or losing the most speed. You can use this as a goal to work towards. For example, by analysing the time in zones of your doped ride, you can see where these times exceed your current capabilities and therefore what to work on to get to those power targets.

In order to make the E-Doper output as accurate as possible, you first load your ride and get the actual and predicted plot as close as you can.

Then you Normalise the data. BikeMetrix will analyse the discrepancies and add additional forces to each data point to more accurately model the actual conditions on the day. This allows the E-Doper to accurately model wind gusts, braking and so forth in your doped rides. It is much more effective if your actual and predicted rides are close to begin with (i.e. use the correct ride configuration and weather conditions for the day the ride took place).

Now you can dope your ride and export it as a TCX or GPX file. The exported file is based on properly modeled aerodynamics and interpolates values for power, speed, heart rate and cadence at one second intervals. Looking at doped rides can reveal some interesting facts. For example, in the doped ride of an out and back TT below, despite adding 60% more power, very little time difference is made on the return leg which is slightly downhill. Almost all the time gains are made on the slower, slightly uphill segments.
