Hello,
I noticed that when doing multisport (like this duathlon) Garmin connect makes completely wrong the calculation, affecting the whole report. Every activity's load, sums up separately, and at the end the sum from the multisport itself adds on.
For example: 1 Duathlon - 400 load, made of 250 cylcling and 150 running, will count as 150+250+400+ the transition, which I don't know why for 3 min, was 184 ( given the cycling was 183). Everything this makes huge impact on the formulas I guess, making the training status absolutely wrong.
You can see what this big graph is made of here:
What's going on - Garmin?!
