Estimating Power with a indoor trainer

[N Coy]

I don't really know what I am doing, but I was wondering if it is possible to estimate power and stress for the performance monitoring tab with only speed, distance, heart rate, and time. I have a dumb indoor trainer and use a speed sensor to get speed and distance data and I tried to estimate power but nothing happens. I really am only interested in stress for the Chronic Training load, but it seems like you need to have power data for that. It's weird that you can add a manual activity, and it will estimate stress, but it won't for an imported activity with no GPS data unless I am doing it wrong. I tried putting the distance and time as a manual activity, but this didn't seem very accurate as comparing it to a ride outside, the bike ride was much longer and farther, and it didn't have much more stress. I was hoping that using the ride data would be a little more accurate.

WRT CTL, if you measure HR but not Power in your training, a stress metric based on HR would be a far better option for the PMC chart, in GC you can use TRIMP for that purpose, see https://github.com/GoldenCheetah/GoldenCheetah/wiki/UG_Glossary
