I'm not saying I wasn't thin. I definitely was. However, you wouldn't have been able to pick me out from a crowd as a 'cross country runner'. And to be competitive at that level, you can't be carrying around any extra weight. While BMI can be a helpful tool, it's pretty flawed. It doesn't take into account muscle/fat ratio. I really don't have much body fat, but am now only 5 pounds away from being 'overweight' accordingly to BMI.

Really, my point was that running 15-20 miles a week won't give you the body of a Kenyan Olympian. Running can be incredibly rewarding, I was simply trying to state that if I had to run 90 miles a week to be barely underweight, 15 miles a week shouldn't scare anyone off if they're just trying to be healthier.
