I have to communicate technical information in a not so technical way to non-technical decision makers with money. Often, this means that I give a view from 1000 or 1500 feet (you'll see why I chose those numbers in just a minute). I have to smooth out some of the details. We call this a "Sales Presentation".
I also have to communicate technical information in a very technical way to the people who will actually be making the stuff work. This means that we get down to the details. We look at it closely enough to see the whole picture while seeing the rough edges of the details. We call this the "Engineering Presentation."
What does this have to do with running? Check out the Sales Presentation of the elevation profile of the Country Music Marathon. This is what I downloaded from their website. They are trying to get people to sign up at the website.
Now, check out the Engineering Presentation of the elevation profile of the Country Music Marathon. This came from my Garmin and is synced up with actual government provided elevation data. This is how I would describe the course to someone who was actually preparing to run the course.
Don't let anyone tell you that this course is easy.
