The fact that they're all running in the same direction--and well spaced apart--helps prevent this image from being too cluttered. The ground serves as a great backdrop. Nice timing with the sunflowers--makes for a good composition.
Nice shot of the Great North Run although brings back hidepous memories of when I ran the London Marathon and was involved in a sprint race with a Pot Noodle at the end (which I won though I am ashamed to say not without the use of my elbows!!!)
Far more sensible to be photographing rather than competing
Neat idea for the challenge. I like how the bees and flowers look so fresh and yet some of the other runners around them look kinda beat despite not wearing silly outfits. Looks like lots of fun, too.
