My knees have been achy the past few days, and that's highly unusual for me. This morning, I figured it out-- for the past week I've been cat-sitting for my brother. So twice a day I've been taking the stairs up to his 7th floor apartment. No wonder the knees are complaining!

Today was an easy 4 miles, with a great view of the sunrise. Almost makes me glad for the heat and humidity, otherwise I'd likely not be out and about so early!
