Pro Great for runners
Fitbit Surge is a good option for avid runners. The wristband is secure and the tracker doesn't fall out. It has a built-in GPS and a heart rate sensor that help to give an accurate estimation of how many calories you burned. It can also withstand bad weather conditions, in case it suddenly starts to rain during your jog.
