A 100-mile radius puts you into regional travel: far enough for a full-day excursion, a weekend loop, or reaching a nearby metro area. At this range you may cross state lines, move from suburbs to coast, or connect to a second airport or rail hub. It is also useful for comparing same-day return plans versus overnight stays. It is a common planning distance for schools, event organizers, and service businesses that operate beyond a single city. The circle shown here is straight-line great-circle distance from your starting point, not a driving route. Roads add curves, detours, and speed changes, so the real drive usually exceeds 100 miles and can take longer than expected. Use the radius map for a quick geographic view, then confirm timing with a route planner.

By highway driving, a rough estimate is about 2-3 hours, but traffic, speed limits, and stops can change that a lot.
No. The circle is straight-line (great-circle) distance. Driving distance is usually longer because roads don't run in a straight line.
The radius is measured over the Earth's surface using great-circle geometry, which gives the shortest path between two points on a sphere.
Where you start changes what falls inside the circle -- coastlines, borders, and terrain all shape what's reachable within 100 miles.
