If your paper rounds is done by walking or on bike, I think you will find this site useful. It is made for sports people.
What you do first is plot your rounds. Easy to do, as you printout a round sheet and plot the addresses in the computer. Then what it gives you such details as the round distance. Then it gives you the calories a person consumed on the run taking into account their gender, age and weight. Then you get the average speed they took. So quickly letting you determine how much exercise you or your staff is getting. I found it easy to use.
If there is much interest, I will create an automatic import from our software.
Here is a youtube describing it with more details.
