My spreadsheet -- any suggestions?

I use Google's My Tracks app for my walks to record various bits of information. I have it set up to save its data to a Google spreadsheet which I have augmented a bit. I'm curious... If you had such a spreadsheet, what additional information would you want to see? I can't do things like heart rate, etc. I'm wondering more about how you'd manipulate and display the data you already have. Here's a link:

The first page of it is just data. The "Stats" page is where I try to make it more useful and explore the data a little.
