Running plan from Trainingpeaks

Hi aIl!
I did a running training on zwift, coming directly from Trainingpeaks.
But for a reason I don’t understand zwift as modified the distances from one of the intervals. Why? And how avoid this?
(I was supposed to run 8 x 500 m, this was correctly mentioned in TrainingPeaks, but zwift modified it: 8x600m)

Many thanks for the support :slight_smile:
