Our 2-step testing system spans two days. On day 1, perform an all out ramp test; on day 2, complete two time trials of 3 and 6 minutes each. Protocols and files for Garmin or Zwift are provided below. Our app will guide you through the analysis process and explain the results.
And yes this is completely for free. Save the $149 or whatever they charge these days and buy some flowers for your girl.
