I started a 5k coaching program and for my benchmark run, my device recorded the 2 minutes of Warm-up, but not the 5 minutes of running. I started the Run session at least three times and ran/ walked for more than 5 minutes, but the Run activity did not stop/ or record on Garmin Coach. On one run my device recorded is as an Activity, but it's not under my Benchmark run. Does this happen to anyone else?
