You probably know I do a lot of walking, I wanted to log my miles but didn't know how to calculate them. Someone from walkingforum.co.uk gave me this link to a site that works it out for you.
route planning and miles calculations
You can use it to plan your routes in advance, walking and driving, or you can check how far you have travelled after your journey. You could use it to monitor how much walking you are doing, especially if it is part of your fitness regime. For instance I know it is 5.25 miles from my house into town. If you are walking to work each day you can total up for the week or month.
I seem to be averaging 9 - 10 miles on a walk, it varies depending on how high I climb. All good fun if you are interested.

Forgot to say, put your start place name in the box bottom right, change the scale to suit, toggle maps if you prefer, I use OS, there is a help button for full instructions.
