Nice composition and great depth of field, but I think that this one is a bit washed out. As arnit mentioned, the direction of the sun gives this effect, but it is easily fixed with a curves adjustment. Giving it a slight s curve would also add the needed contrast and probably bump this one up a full point. Your composition works very well, drawing the viewer's eye down the path to the next biker, while still isolating the main subject. Your choice of subject and cliche make this fit into the challenge very well. Overall, nice work that could be even better with some slight adjustments.
Because of the sun shingin towards you I find the picture a bit to light. I like the composition and how the bikers lead my eyes into the picture. Good job and good luck.
