Not sure if this has been covered recently (I'm reading the entire thread and it's long!)? I'm getting to the point in my running where I need to improve on a few things, like strength and speed. And it occurs to me that I need solid data to do that properly, such as HR and cadence readouts. My question regards running watches, wearable bands and smartphones. I don't have the budget for a good running watch (R2000+ ?) so I'm looking at used, or alternatively a wearable (Samsung Fit) tethered to my phone. I essentially want run data sent back to Strava, and also heart rate and cadence threshold alerts while running. Can I ask you experienced runners what works for you? Are tethered devices viable (they seem cheaper if you have the phone already), or do they come up short?
