Default Cyclingpeaks Question

Does anyone have a suggestion as to why n/a is shown as my TSS rather than an actual value?

I got the same problem. During a workout, some of my intervals had N/A for TSS, other no.

It might be worth contacting CP direct.

Try saving the workout file and then go back and check your workout. Saving (from the athlete homepage) updates the charts and datasets.

How long were the intervals? There's a minimum time for Cyclingpeaks to calculate NP. To the OP, have you entered a value for threshold power? Without one, CP can't calculate NP, IF, or TSS.

Selections less than 30 sec in duration won't have an NP, or likewise a TSS value, because of the averaging interval used in the calculation.

Thanks frenchyge and asgelle ! You are right, I did 30s interval but several were just below (29.8s), and I forgot the NP calculation rule of 30sec.

FWIW, I wouldn't trust normalized power for any effort <5 min in length (and in fact will lobby that this be changed in any future version of CyclingPeaks).
