I had to try it! I had to know! and I did it! I ran 13.3 miles today. Now I know for sure that I can finish a half-marathon.
I strapped on my son's GPS watch and went running through Dana Point Harbor; from the Marine Institute to the end of Doheney State Beach, over the bridge around the island, between the boats, through the shopping villages, and past all the people sitting outside having lunch. It took me 2 hours and 23 minutes to finish my random course. I'm not too disappointed with the time, I'm just so happy that I made it!
