| as stated, it depends on your stride and your pace.
most people can average between 3-4 miles an hour without extensive work... for ex, i workout 3-4 times a week. 3 miles per hour (20 min mile) is easy... while 4 miles an hour (15 min mile) seems fast for me for walking, though i prefer faster spurts of running (6+ mph). my wife has longer legs, and is a runner... 4 miles an hour is a reasonable pace for her for walking while i have to work hard to make it be ok.
so... it comes down to your pace and stride and fitness. a 45 min mile is about 1.3 miles an hour... something that is really reasonable for most... and honestly, if you are in moderately ok health, i dont think 3 miles an hour pace (20 min) is unreasonable... and most can do closer to 3.4 + with some effort. |
