What is an out-and-back route?

An out-and-back route goes in one direction and returns the same way. Your turnaround point is exactly half the total distance.

Is a loop or out-and-back better?

Loops offer more variety and avoid repetition. Out-and-back routes are simpler to plan and let you easily adjust distance by changing the turnaround point.

How do I measure a running route?

Use online tools like MapMyRun, Strava Routes, or OS Maps to plan and measure routes. Most GPS watches also record your route for future reference.
