First Time I took Photos at a Track Meet

Yesterday, I had the chance to go to a Track meet and take photos. I have never taken photos at a Track meet. I have taken photos at a football game before. I really had no clue what settings is best for photos of running people, so I did some research and the website I clicked on was very helpful. The website gave 12 tips and I used 2 of the tips. It said to have ISO at 800 or 1000 and shutter speed at 1/320th of a second. So when I got there I tried ISO at 800, shutter speed at 1/320 and I knew from previous research that the focus should be a higher number. So I changed my focus to F9. I think I did I pretty good job for my first time. 

All photos, ISO 800, Shutter Speed 1/400, and Focus F9
