Zane, my youngest son, ran in the Barkley Marathons this weekend at Frozen Head State Park, TN.

He started at 7:15 AM on Saturday with the temperature at 30 degrees. Sunny and clear. This lasted all day and into the evening.
Zane finished loop one of the Barkley in a bit over 12 hours. He went "out there" on lap two in the dark and by Sunday morning when he returned to the start/finish line he has spent the night seeking to stay on the unmarked course with some difficulty. He had six of the 10 pages from books and was running out of time. It was raining and that did not help as it slowed travel even more.
Here are some photos from Day 1 and 2 of the Barkley: http://cid-465e8525eded80a6.skydrive.live.com/browse.aspx/Barkley%20Marathons%20100%20-%202010?authkey=4QvCCYnijHQ%24&ct=photos
