Thanks for the comments. The shot under the hurdles is one I like, but don't take very often because it's getting harder and harder for me to get up off the ground quick enough with the big lens to be out of the way. On that second one I was watching the warm ups and noticed that both girls next to each other led with opposite feet. In a perfect world the one on the right would have swung her left arm out so the image would have been more symmetrical instead of looking like she was amputated. Getting the rest of the field in the shot was a no go since they were two strides behind these runners.
ZapoTex, no problem on the edit. I don't mind seeing what others have in mind and using that in the future.
Imagemaker, I also like the 3/4 angle from the side for single runners. With two of them running a near dead heat that doesn't work as well as one runner gets lost behind the other.
thanks again for the thoughts, it's all tools to put in the box for the next time out.
