Hi:
I'd love to get some insights from people who are more expert on the analysis that Garmin has done around training. I'm training for an Ironman and I'm mixing cardio training with HIIT, endurance work, and strength training.
On Saturday, I did a 70 mile ride and then a six mile run. After that, my watch said my training is unproductive. I don't have a power meter on my bike, so I'm wondering if the watch is only really looking at my heart rate and GPS on the running. Naturally, after a 70 mile ride, the kind of run I'm going to do is going to be of a lower performance than what I'd do if I was fresh.
Should I ignore this or am I doing something fundamentally wrong in my training (keeping in mind I'm a newbie to Ironmans - have done one half only before).
Two related issues:
1. I also observed that my VO2 max declined from 54 on Fenix 3HR to 49 on the 5X.
2. To what extent do the Garmin algorithms care about strength training, where you're not doing cardio.
Thanks all for your insights.
