Trail note: It's a picture perfect late afternoon: blue skies with just a few puffy clouds, temp high 60's, breeze, yet enough haze so that the mountains are only a blue shadow on the horizon. I did the "around the top of the hill" route; 4 miles w/ hills and stairs. I was worn out. I guess it was the yoga. I did well on the hills (more than usual), but just didn't have much "get up and go." I should have gone a couple more miles, but was glad to just have gotten out at all.
