Felt much better today, didn't start to feel tired until 8.5 and the I-want-to-stop tired didn't come until 10 miles (that usually comes around 6.5 miles). I think it's because it was flat (cemetery run), and I got a lot of sleep last night (not intentional. When I woke up I was so surprised at how long I had slept, but I guess I needed it!) 7:53 average.
