Thanks for this thread and I agree that it’s hard to keep up with TSS on outdoor rides. I have PowerTap P1 pedals for my road bikes but can’t use them on my gravel bike as I use MBT shoes.
I did a ride last weekend that I’ve just got no clue how to estimate. 2 hour ride, 24 miles with 2 significant climbs and descents. So one big climb working my tail off…then descend for a good while. Then a KILLER climb for 45 min and then more descending that’s nearly no effort on the legs and done.
