I ran 13.1 miles this Sunday. I did it up hill, then down hill, then up hill, then down hill again and a gain and again. It was difficult. It was cold. It was windy. It was challenging. The scenery was breathtaking. I cursed myself outloud at the base of each hill. Running up hill for almost 2 miles in San Francisco is SUCH A RUSH! I'm still high off of my accomplishment. 13.1 miles in 2 hours and 17 minutes. and 40 seconds. Nike Women's Half Marathon, San Fracisco, October 19th, 2008.
