From the beginning of December last year I have gotten some extremly high loads (like 6-800 from a single workout) from my activities. They are mostly running activities done with HR and Stryd power. I have used this set up for the last years so it is not something I changed at that time. Could you look into this to see what’s wrong?

Will do. I am looking into this at the moment. Other people have also had problems.
Have you looked into this? There are several activities with abnormal load load value like this one:

This particular activity was a short hilly trailrace.My gut says it has to do with runninpower values coming from Stryd for some reason and that that value is used to calculate load even though it is labeled as a running activity. My FTP for runningpower FTP is around 335w while my bike power FTP is around 290w.
Interestingly this does not happen to all activities that has Styrd powevalues
I am working on training load for non-cycling activities with HR this week. I am implementing the formula that Elevate uses which apparently gives very similar results to TP hrTSS.
The models based on cycling power and HR data don’t generalise very well to running for quite a few people.
Hi David, I just invited a friend to intervals.icu and three of his recent rides have strange load values. Could be related?

Eesh. That is something else I think. Looking into it now.
I can see whats wrong. I will sort it out tonight as part of the HRSS work. Sometimes the model ends up with way out coefficients (which I can detect) so I will fallback to HRSS in that case and also require more data before using the models.
The HRSS stuff is live and I have fixed up your friends data. Sorry about that.
Intervals.icu was using HR data for that and the cycling model wasn’t doing too well on your run. The new HRSS stuff (from Elevate) does better. I have fixed that activity. If you capture your resting HR in /settings all the others should be fixed up in a few minutes.
I am going to deploy code just now to fix everyones stuff.
That isn’t causing any trouble because Strava has “device_watts: false” for the activity. So Intervals.icu displays the power on the timeline chart but doesn’t try and use it for anything much.
I need to do some work there. I could display all the activity power data like for cycling. I need to find out how comparable Stryd power is to a real PM on a bike.
For the last week, my runs have had no training load. I’m still wearing a HR monitor and haven’t been using any new GPS recording devices.
See examples here.

Hmm. Somehow your HR zones have been lost so you are no longer getting training load calcs done on your HR-only activities. You used to have HR zones as your older runs have training load. You need to go to /settings and re-setup HR zones. Do it once and then make an edit and tick the “Apply changes to all …” box. That should re-calc training load.
I really have no idea how this happened 
Such an easy fix! Thank you for your help
Tx. Hopefully it stays fixed. I couldn’t reproduce the problem that wiped out your HR zones int he first place. I think it must be rare at least or there would have been more reports.
