A guide to going under 3 hours
Although you can use Google Earth or other online map services to look at your routes, there is one site that comes in particularly handy - the GMAPS Pedometer page.
According to its website, the Gmap Pedometer website is a "a little hack that uses Google's superb mapping application to help record distances traveled during a running or walking workout."
It's a fantastic tool which helped me to plan and measure routes, especially once you start doing longer runs which require a little forethought about the route.
