Training Effect discrepancies Edge1040S vs Epix Gen2

Garmin, Team

I recently recorded the same bike ride using both - Garmin Edge 1040S and the Garmin EPIX Gen2

The setup:

Garmin Edge 1040S - latest sw. 23.10 (auto start/stop enabled) (https://connect.garmin.com/modern/activity/16331946793)
 - Garmin Speed sensor 
 - Garmin Cadence sensor
 - Garmin HR Duo strap sensor

Result says benefit is: Base 
2.9 Aerobic
2.4 Anaerobic
84 exercise load

Garmin EPIX Gen2 - lastest sw. 17.28 (https://connect.garmin.com/modern/activity/16353949502)
 - no sensors connected (just running the watch with the same auto start/stop)

Result says benefit is: Sprint 
3.0 Aerobic
2.6 Anaerobic
97 exercise load

HR, distance, speed, av speed are very much the same, calories, etc .. - small discrepancies that I believe to be acceptable.

Is this training effect discrepancy within acceptable results ?
Thanks

  • Since they used different data you will get different results. The differences are not huge. What got most effect is the use of a chest strap. For biking optical heart rate is not recommended to be used. Too easy to get errors. 

    Next time connect all sensors to both devices.
