Beginner, short distance (say 10-15 miles): average speed 12 mph. Most cyclists can achieve 10-12 mph average very quickly with limited training. More experienced, short-medium distance (say 20-30 miles): average 15-16 mph. Reasonable experience, medium (say 40 miles): average around 16-19 mph.
Stride length is measured from heel to heel and determines how far you walk with each step. On average, a man's walking stride length is 2.5 feet, or 30 inches, according to Arizona State University Extension. A woman's average stride length is 2.2 feet, or 26.4 inches, reports the school.
The length of an average walking stride is 62 inches. People frequently mistake stride for step length, or wrongly assume they are one in the same. Step length is defined as the distance between the heel strike of one foot and the heel strike of the opposite foot. On the other hand, stride refers to the consecutive heel strikes of the same foot.
