Maybe I have done something with out realising or I'm being totally thick but today, like every other day I went for my run. Indoors on a treadmill (as I work onboard a vessel) but today for some strange reason it recorded my session... but with zero calories and with zero distance. During my run it told me my pace and the length of time I was running as well as my heart rate as they are the options Ive got set but the distance and calories just say 0. Can anyone advise me? Thanks David.
