Self portrait as a start for a new project

Decided to make a self portrait directly after my run. In some way it must be possible to see it back in the portrait. There must be a possibility to see a change in the eyes. To find out if it's true or false, I'd like to take some portraits. I'm looking for persons who'd like to run with me or do some other sports and have a photo taken before and afterwards. It doesn't matter how good you are, as long as you try to challenge yourself and aim high (faster, longer, better).
Didn't make the self portrait before running. This one is made just after the run.
