How to Measure 3.14 miles

GPS: One of the easiest ways to measure is using a GPS watch. Aim for 3.14 miles or 5.06 km.

Online Tools: Two simple run-mapping websites are On the Go Map and Map My Run.

Track: If you're on a track, run 56 meters past 5 km. On a 400-meter track, this is 12.5-laps + 56 meters.

How to Record Your Results

Keep track of your time however you like (style points for effective use of an hourglass). When you're done, upload your results.
