Hi Scott,

what are the upper-value limitations?

Regarding my motivation:

The IF determines TSS. TSS is important and the Uphill Athlete recommendations go through great length to adjust TSShr for weight, downhills, etc. Understanding the calculation will help me put it into context.

Originally I stumbled on the topic because my running TSS would never match my hr TSS, even when doing low intensity constant effort on flat ground.

The formulas for running TSS are public, for hr TSS the support dodges the questions.

By now I’m closed to convinced that there is conspiracy going on to hide the fact, that the calculation is wrong 😉

Anybody got an idea?

Cheers,

Alex

Hi Scott and Reed,

Thank you for the replies!

I agree with both your comments and have been through all the resources I could find regarding TSShr, so I also know the pitfalls.

Nevertheless I want to understand how the IF is calculated when using heart rate. It should be rather straight forward, but it’s not.

Anybody has any ideas?

Regards,

Alex
