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.
Although there are numerous ways to calculate your stride, the simplest way is to walk ten steps, measure the distance traveled, and divide that measurement by 10. Required tools include a tape measure, chalk or other marking device, and a calculator. This process takes less than 5 minutes.
