I am used to run a lot. All the time outdoors rather than on a treadmill. Therefore, speed control is a little harder in my case.
I realized that my speed is far from being great, so I want to work on improving it. Of course, I can try and control it in general by pushing myself to run faster. However as another way to put more control of the speed would be some gadget that can accurately measure current speed, and, provide a low limit setting so that if my current speed falls lower that this limit it will notify me by beeping (for example). My question is if there is such a gadget that people use?
PS: There are mobile apps that "measure" your speed, but that number shown is an average on some interval of distance since all of them just use GPS for distance tracking and divide that distance by time interval between measurements. So mobile applications or GPS trackers are pretty much out of the question here as they won't be able to notify me immediately on speed being too low.
PPS: Have anyone tried Polar Footpod for this purpose?
