FIT file will not upload.

I have a run that seems to be somehow corrupted. Trying to upload it manually results in an error saying "One of your files was not accepted by the system. Please contact Support for assistance."

The activity can upload to TrainingPeaks just fine, so not sure if it's a corruption issue or something else.

My watch battery died shortly after completing the run, perhaps that has something to do with it?

Normally, I'd just forget about this and move on, but this particular run is my first 100k, so I'd really appriciate any help getting this activity uploaded.
