I went out and ran a half marathon today. It felt terrible right from the start. I had to force myself to just keep going. I had measured out the distance earlier in the week on my bike. I ended up running out Martinelli and taking the bike path to the Graton water treatment plant. It took me 1 hour and 40 minutes. My knees were hurting pretty good at the end of the run. That is all I have to say about it.
