The long run, according to US Olympian Jeff Galloway, “will help you more than any other component of your training program.” It is an integral part of marathon and endurance training. But how do you plan and measure your long run route without having to go out and use an odometer, pedometer or global positioning system (GPS) device?

It’s easy. Use Google Maps.

google-map-running PLANNING, MEASURING LONG RUN ROUTE. Google Maps allows you to plan ahead and measure your running routes. Above is the route I planned for our two-city long run this Sunday, Nov. 1. Click on photo to view larger image.

Google Maps offers two tools that allow you to trace a route on a map, satellite image or a composite of the two, and then measure its distance. To use the tool, log into Google Maps using your GMail account and then click on My Maps and then choose Browse Directory.

You will then be presented with several add-ons to your Google Maps account. You can either pick Distance Measurement Tool or Area and Distance Calculator. I’ve long been using Area and Distance Calculator but I recently tested Distance Measurement Tool and found it to be better. Click on the Add it to Maps button below the tool area.

After adding the tool, just load a map and start tracing your route. The panel on the left side will keep updating you on the total distance of the route you are tracing on the map.

Is it accurate?

In my experience, yes. I plan out Marlen’s and my Sunday long runs using Google Maps and then use a Garmin 205 for the actual run. The variances in distance are negligible.
