Not so great today. Weather was better than I can ask for in LA on the last day of July--nice refreshing breeze. But I bonked about 4 miles into my ride home. No idea what went wrong, but I thought I was going to puke or faint or something so I sat by the side of a busy street in a questionable neighborhood for about 20 minutes. Then it was a real trudge for the next 10 miles. I didn't really hit my stride until about 2 miles from home. After all that I wound up with an annoying case of chafing. WTF?
