What are the best practices for setting up a ride to get my Estimated CdA?

While any ride that has GPS data, power and speed can be analyzed, a few extra steps can help get the most accuracy out of the Estimated CdA functionality of the Race Analysis Tool.

  1. Calibrate your power meter before the ride
  2. If possible use a dual sided power meter
  3. Record your data with a head unit or watch that has a barometric altimeter for elevation accuracy
  4. Use a speed sensor instead of relying on GPS for speed data
  5. Have an accurate weight of your bike in full race setup (not just advertised weight)
  6. Weigh yourself in full race/ride kit
  7. Make a note of the general weather to spot check the historical weather data we pull
