A large portion of people in the USA do not live 5 miles from a grocery store. DGs and family dollars don’t count as a grocery store either, even though a lot of them carry food (these damn things skew distances for a lot of people).

On top of that, 5 miles gets you there…5 more miles gets you home. Average cyclist does like 10-12 mph, that’s around 25-30mins to get 5miles. So just going to the store and back is 1h cycling.

Good workout, not practical.
