TIP  Stride length is a distance between the tip of toe of your leading foot and the tip of toe of your back foot while you walk a 

pace, or also can be measured by the heel of your feet as reference. For correctly measuring individual stride length, you can 
walk a distance at your normal pace, and then being divided by the paces, the average value can be used for inputting into the 
watch as a stride length. 

For example, the total paces of your walking are 10, and the distance is 230 inches (584.2 cm). Therefore, the average stride value is 23 inches (59cm). 

Total distance ÷ Steps taken = Average stride-length

230 ÷ 10 = 23 inches

There is a formula to calculate your stride as well , please see below:
