Elevation troubles during Vacation

So I have ran the last two days while on vacation and have had a really really difficult time with it. I was not sure if it was the hills, being tired from travel, not eating right during travel, or all of the above. 

When I did my second run I paid REALLY close attention to the way I was breathing. I noticed that I had a difficult time keeping my normal rhythm while running that I do when I am in Alabama. It felt like I couldn’t get enough oxygen. But why?

I knew it was not the humidity. So I started thinking. The only difference that I could think of was the elevation. So I started doing some research.

I found a website that allows you to put in an address and calculate the elevation. According to this website, I am elevated 545 feet higher than I usually am. So what does that mean?

Then I found this article that talks about running, cycling, and elevation. There is a chart on the bottom that explain that me having a difficult time is normal and then a paragraph that explains it. 

So the mystery is solved and when I run tomorrow… I’m not going to be so hard on myself :)
