Here's a hairy one. The Appalachian Trail, which runs from Mt Katahdin in
Maine to Springer Mtn, GA is only 1,120 miles as the crow flies. With all
the switchbacks and ridgelines, the trail is far from anything like a
straight line or road system (thankfully). Actually it almost twice as
long, with an actual distance of 2,104 miles (ratio 1.879!!)
Takes about 5-6 months to do a thru hike, my feet ache just thinking about
it...

The ratio will depend a lot of the length of the route: Longer routes
will generally have a ratio closer to 1. Urban routes is also likely to
be closer to 1, since the road network is more dense in towns.
Mine is 6.2 km / 5.6 km = 1.11. This is very close to a straight line,
when you look at a map.
Kind regards

Subject: MI-L weekend question: ratio between like the crow flies and
road distance
Hi out there,
on my push bike, I have a Garmin Geko 201 mounted on, which is a
wonderful device.
Since it does not have street data on it, I am navigating with compass
directions.
The remaining distance the unit returns to reach the desired waypoint is
of course like the crow flies.
However, as a cyclist, I stick to the roads.
Does anybody have experiences which the common ration between the
straight distance and the road distance is?
Sure, you are right if you say: depends on the road network!
However, for the region I am living in ( 7�13'13"E 51�29'18"N ), I
experienced a more or less constant factor around 1.45 .
To make it sound more scientific, I ll simply call it square route(2).
Does anybody have values for other regions?
Cheers
Christof
