I have just discovered this rather handy tool from the Good Run Guide – the RoutePlanner – where you can map out a track and find the correct distance. This is really useful when Google Maps only wants to give you directions and distances for the road routes or more obvious pedestrian areas.
I figured it was not just for runners but would actually come in handy for measuring any distance that you need, and if you create an account, you can save your work and revisit it whenever you want.
All you have to do is click ‘start’, choose a position to start from and then clickety click your way around whatever it is you want to measure. You can even choose between measurements in miles or kilometres. Super handy and not just for runners.
