Reset my PBs as I realised stopping and starting my watch wasn’t really giving me accurate times. Relying on the auto-pause feature from now on.

I started doing the opposite as I found my Forerunner always had a delay on my pace that meant it didn’t detect starts or stops quickly enough to give an accurate time. Manual works a lot better for me. I ran a 12 km recently and my manual start/stop time on the watch was identical to the official race time, which is crazy after an hour of running.
