I use Intervals to capture all training to track my overall load.
Some sports I do are not structured sessions and I use the ‘Cardio’ activity type on my Garmin forerunner 55 to capture hr data (indoor activities like ice hockey and floorball).
Sometimes automatic interval detection works and sometimes it does not.
For the activity below I cannot even set intervals by hand.
All activities are synced via Garmin Connect.
Those would typically not be very well suited to calculate load from HR because they are highly variable and HR can’t catch up. But I’m afraid that there are no other alternatives…
?? Why not? Maybe you didn’t notice that the whole activity is one big Interval? In that case you can’t ‘Add’ an interval because everything is already within an interval. But what if you set mouse cursor at the start or end of a portion where HR picks-up, and you hit ‘S’ to split the one big interval at that point? That should work…
Or hover mouse over the chart and press D to delete the one big single interval and then start adding intervals as you would like.
In the “Actions” menu at the bottom you can also use “Find intervals” and select the “Heartrate” option. If you tweak a few of the parameters, to suit your case, it’ll likely save you some clicking, or at least use it as a base line for further refining.
Thank you for replying.
I understand its not ideal but I cannot see any other way of keeping track of my overall load.
A good week i might get 200 in load from my structured running workouts and 150 from two indoor sports sessions.
Since I can plan them as structured sessions I have made one long block for planning purposes. So that I can see what my overall load will look like when i plan a few weeks ahead.
About hr lag etc: My current watch does not measure running power and even if i did i guess it will look rather strange since its not running in the same way as on a track, especially not ice skating.
My posted image is a rather good representation of a sports session with high intensity on and short rests when substituting.
How could I improve my estimation of the load these sort of sessions provide?
The reason for me tracking and planning is to improve my 10km run, want to get sub 40 min before i turn 40! 
again, thanks for your comments
I tried this but it did not work. Perhaps the background planned was in the way. I will try to delete or split it
