When i upload my workout, Trainingpeaks does not calculate my normalized pace. What am I doing wrong? Do I need to change some settings?

I have a premium subscription, workout recorded with a Garmin 735XT och synced with Trainingpeaks from Garmin Connect.

Thanks DJ Faithful! Never realized that threshold pace was part of the calculation on normalized pace. Thought it only had to do with elevation.

Thing is that the workout was my first LTP-test so I didn't have a threshold pace before. Used Friels method of running 30 min as hard as possible.

I entered my avg pace for the 30 min test (4:25/km). TP calculates NGP = 4:06/km.

Should I change my threshold pace to 4:06/km?

DJFaithful has got it all backwards here; your TSS value is being calculated from your heart rate (hrTSS) because you don't have an NGP calculated for that workout, or because you don't have a threshold pace set, not vice versa.

As you say, TrainingPeaks should calculate an NGP for your workout regardless of whether you have your threshold set or not, which would suggest that something is up with the data from that workout. Can you post up the chart of your data, is the elevation or pace all over the place? If it's too erratic (read: noisy data/spikes) in either pace or altitude then the NGP calculation won't work.

If your all out 30 min test interval was reasonably flat and evenly paced then for all intents and purposes your average pace will be the same as NGP and the same as your threshold (according to Friel's method).

I removed my threshold pace from settings and recalculated the workout to show you what I was looking at when I first posted. The value for normalized pace disappeared when I recalculated.
