On Oct 31, I ran 8.1 miles to reach the 100 km goal for the month. As usual, I started the run on my Apple watch 3, so I could monitor heart rate and pace. I wear my iPhone X in a Nike armband for GPS. At the end of the run, it never synced back to my phone: usually just a few minutes after I finish a run on my watch with my iPhone with me, the run will show up in the NRC app on my phone so I can apply it to my running plan, and enter my effort, where, and notes. It never showed up in my iPhone NRC app, so it looks like I did not complete the October 100km challenge. I called them about it, and they said it was a known bug, they were working on it, and would be in touch with me in a few days. Today, I held the phone in a hand strap case so I could use the phone screen easily. I did a QuickStart Run (warmup), then a Speed Run (6x400m), and then ran home with another QuickStart run. For all 3, I had NRC open on my watch and phone, but _started_ the run on my phone, which in turn started the run on my watch! This way, I could see ongoing heart rate on both devices, and could push the Lap button on my phone at the end of the 400m reps. I do prefer being able to simply Start a run from my watch and Apply it to the Plan later on my phone, but for now, this is a work-around.
