Yesterday I went out at 4pm and decided on a flat run by the Bridgewater Canal. I ran the first kilometre, didn't feel too good, so walked the next 6k, which was very pleasant. It might have been the extra humidity beside the canal that did for me.
Today's a whole different matter. I had a banana at 9am, then went out for a 17k (10 mile) slow run. It was a cool morning, absolutely lovely. I'm tired now though.
It's funny how some days you just don't feel like running, but the next is completely the opposite.
