(That's me in the black)
I just got back from running the San Francisco Nike Women's Marathon. Wow....what a time! That was the hardest race I've ever done. I was not mentally or physically prepared for that. I also should have checked the elevation chart on the course map before I went. The whole thing was up-hill. OUCH! Luckily my knee held out and I didn't have any further injuries, but my legs turned into bricks halfway through. I missed all 3 of my time goals (my 3rd one by 28 seconds). But I finished and I got my Tiffany & Co necklace and had a wonderful experience. It was so beautiful! I would do it again with a body that's better trained for hills.
