I am a complete novice with any of these kind of devices so please be patient with me :-) I just set off on my first run using this watch and after 4 and a bit km it abruptly told me that my workout had finished. It also kept telling me intermittently that I was 8 something ahead. Ahead of what? I haven't knowingly set any target/limit parameters and can't see where I might work out what happened and how to correct/remove them. Any help gratefully received. Thanks.
