Seriously, I have written in posts here before about the wider benefits of this programme. Bought new Fitbit Surge after lots of deliberation. Had thought you could not have more than one Fitbit registered at once and like my little Charge for day to day activity level monitoring( note to self, check the date of stuff you read on the net; this was already out of date last year duh). So that was sorted. Anyway seems it has been registering my resting HR at 55. Looked at a chart on the net which ranks by age, gender. Seems for 55-65 woman am in the Athlete category (by one beat, but hey). I know a lot of us still fret about how far and fast we are going, but seriously. This is a true benefit and it is definitely the running that has done it. So, to any newbies out there, I would just say " think wider benefits" and trust the programme!
