I’ve only been in the Beta since yesterday but have checked a few outdoor rides utilising the new HR TSS estimate and have also found it to be high.
I sent a little explanation to TR Support today:
…you appear to have an HR based TSS estimation for outside rides now. I have been using the Strava/Stravastix/Elevate TSS estimation for all of my outdoor rides. However, I have just checked a few using the TR HR estimation and there seems to be a considerable discrepancy.
For example. This mornings outside ride got 38 in Strava, but 62 in TR. And a previous one got 39 on Strava, but 64 in TR. Comparing this to my indoor trainer rides, this doesnt add up. For an hours VO2max workout I am getting approx 60-70 TSS and for an hours endurance, around 35-45. Based on HR, and endurance ride is about Average 130 HR whereas a VO is average 155 with a peak of 175 ish. Therefore for an hour outside, where I am averaging 130 and a peak of 155, you would expect it to come in around 40 TSS, not 62?
Bit rambly but you might get the idea
