I can almost feel the sweat for them, too energetic for me to partake, good shot.

The clarity is so good in this pic that you can see the determination in these guys' faces and the muscles bulging with the effort!!! Your composition is also very pleasing as it pits both subjects against each other from one side to the other in the foreground and lets us view the other elements in the background without distraction. The color contrast between the deep greens of the trees and the lighter shades of white, tan and brown is pleasing and there's no doubt it is all combined for an excellent view of the action. I got interested in this and where it was, and I found a link that I've provided HERE Thanks for sharing this look into the past recreated in the present :)PJ

Thanx for all the comments. These guys are professionals and this might be for a show but they are very serious at heir job.
