Like the high contrast and black and white aspects of this photo. It is concise with no distracting stuff in foreground or backgrand. Nicely cropped. Good job!
I like this photo. Just my opinion, (and I know you can't always control the situation), but it would have been even better if the approaching runners had been editied out-- would have given a feeling of going into the unknown. Great sky, great tree. Great job.
