HI there
If anyone is looking for a great site to track your walking, biking, running...I have found a great site. MAPMYRUN.COM

You can look for courses that others have done and have saved for others to look at or you can put in where you want to go and it will tell you how for you have gone. It is also great to put in where you have gone and then play with the maps to see how you can make your walk longer. You can have buddy lists and share with them your pregress and all sorts of fun things. The best part for me is the challenges. Right now I am working on the Walk a Marathon in a Month. You alos have the option to have the sight send you reminders of your challenge daily, weekly...your choice.
I encourage everyone to check it out.
