Here is another photo of some of the many dedicated runners in the recent P.F. Chang's Rock & Roll Marathon.
Most runners wore caps or hats, but some did not, even if they had heads that are shaved or bald like the runner in the foreground of this photo. I hope that he has a high spf sun block on his head. Running at least 3 hours in the Arizona sun without sun protection would likely cause a sun burn, and skin cancer is a big issue in Arizona for light skinned people who do not take precautions.
This week we have photos of the wildlife of Africa posted on our Viva la Voyage travel photo site.
