I am part of a team on Sparkpeople that does Virtual Walks it is called
Where are YOU walking to?
This is a virtual walk! Choose your destination and find out how many miles it would take for you to walk there, then hop on the treadmill (or sidewalk) and start tracking the miles you've walked.
In the team we count the miles we walk in a day and total it up for the week that way we have an idea as to how far we gone. As we are doing it this way it will take a while to complete the walk so I am keeping mine a reasonable length so that they are a more interesting. After completing the Trail I will choose another walk that will also be to a place of interest in England.
