These are from miles 11-16 of the Diablo 50M race. By the last picture it was starting to get really warm and Steve and I parted ways and I put my camera away and focused on the task at hand.
I did the second half slower than the first half, but managed to pass about 15 of the people who were ahead of me at the turnaround.
Going back up Diablo at a speedy 24 minutes per mile (!) and I was passing folks "easily".
No one passed me after mile 10, but with 3 miles to go another runner suddenly showed up right behind me out of nowhere.
Bummer! I figured if he was going to pass me I was going to make him work for it. I put myself into a gear I didn't think I still had and finished 1/2 minute ahead of him. He's probably still laughing about it.
