A group of 9 National Geographic staffers are walking 200 miles in 10 days with only water and one teabag each– no food. They are camping out during the day, walking at night to aviod the heat. Their object is to raise
$10000 each for the Afghan Girls Fund, a charity established in 2002 by
the National Geographic Society after photographer Steve McCurry went back to Afghanistan to try and find the green-eyed girl in his famous photo years earlier. The Afghan Girls Fund is building schools and training centers in Afghanistan. This fundraising walk is not sponsored by the National Geographic Society, but all the walkers are employees, and the walk will wind up Thursday around 4pm at National Geographic hq on 17th and M Sts [in Washington DC].

One of the walkers has a 13-year-old daughter who’s blogging the trip.

Here’s a Washington Times story on the effort.
