Flora London Marathon route on GMaps

I have mapped the Flora London Marathon route out on Gmaps pedometer to send to my family so I can suggest where to stand and watch the race from.

It gets very crowded and runners come through in a mass, so I've found it helpful to know where they will be and which side of the road you need t run on at that point.

If you haven't used Gmaps pedometer before, it's dead easy and helps you plot how far your run is going to be.

You can see from this plot that it's not 100% accurate - giving the Flora London Marathon route as 26.39 miles - but that's less than 1% inaccuracy over marathon distance, which is pretty good.

To mark out your own course go to the homepage, use 'Jump to' to select the country and town where you want to start, zoom and drag the map to your starting point, then click 'Start recording'.

Double-click on the map to set your starting point then at each turn double click again to draw a straight line between the points. You'll see the distance rise on the left as you go. So simple.

Enjoy.
