Running for Refugees

Did a Google image search for something to use for my last update...you know someone crossing the finish line since I'm almost finished this challenge, blah blah..

So I do as everyone does and Google an image and I get a bunch of business people running, which raises some really important questions:

a) who uses these images? and why?

b) can you imagine being one of the models..."okay guys, so imagine you're literally in a race for business success, now game faces on"

c) why are there so many?

d) which one should I use :)

On a serious note, I'm totally going to try and replicate some of these poses as I cross the finish line this weekend
