Walking and running — both are good forms of aerobic activity, and both have their advantages. They have many differences, to be sure; here’s one important difference.
But know that whatever form of motion you choose — walking, running, unicycling, roller skating — you’ve already achieved a goal. And that’s the goal of being active. Congrats! (And may you burn some calories in the process.)
The fastest 5K time clocked by a female walker is 21:58 (about a 7-minute mile) and by a male walker, 19:09 (about a 6-minute mile) — faster than most runners! For those who don’t remember their metric conversions, a 5K equals 3.1 miles.
