Records for people at least 35 years old are called "Masters" records. Since our ability to intake and process oxygen decreases with age, records are kept in 5 year age groups. This doesn't mean that Masters Walkers are slow. Far from it. The US record for 20km for men aged 60-64 is 1:51:17, for an average of about 9 minutes per mile or more than 6.6 miles per hour!
For Comparison
A typical club walker (under 50 years old) with moderate training will walk 5km in 36 minutes, or 11½ minutes per mile or 5.1 miles per hour. With significant regular training, a typical club walker can walk 5km in 30 minutes, or 9½ minutes per mile or 6.2 miles per hour
An ordinary person out for a walk averages about 16 minutes per mile or 3.75 miles per hour. A fitness walker tops out at about 12½ minutes per mile or 4.8 miles per hour.
