Better Ideal Weight Body Calculations

I've been running at lunch this week. I have a 3-mile and 4-mile route that goes across the dam at West Point Lake. I wish I could run farther, but I only have an hour for lunch and need to drive back, shower etc. I put up a photo of the turnaround point.

2.8 miles every day last week. It's been cold.

I have been using a spreadsheet lately - I'll put it up pretty soon.
