I am currently running on a treadmill which is super smart and not only gives me my speed etc., it also tells me my heart rate. Because I am considerably overweight I like to check this several times during both the running and walking segments (to check it's not too high/coming down well). Can anyone suggest an app/fitness band that will be able to do this for me when I'm not on a treadmill? Also ideally one that can tell me what speed I am running at any given time? Finally, is there an app that can map out a (say) 5k run for me, in my area, in advance? I downloaded MapMyRun but that seems to only be able to record a run that you've done (although its entirely possible that this isn't the case as I'm not very tech-savvy). Thankyou!!!
