7.5 mile long run

I had to do my long run today, because tomorrow we are spending all day at the Brookfield Zoo in Chicago with the kids.  I will "zoo walk" for my cross-training.  We had a horrible storm last night and it was overcast and very humid today.  Overall, I had a good run.  I ran into trouble in mile 5, when I went down a path and about 50 feet down the path I discovered the trail was washed out.  I stopped and tried to wade through the water, but it was too deep.  I had to turn around and run back to the main path and back-track.  This was very depressing because it also meant running back up a big hill.  My times were as follows: 9:52, 10:02, 10:05, 9:58, 10:07, 10:25 (the bad mile 5), 10:04, 5:00 (for last half mile).  Total time was 75:37.  I felt pretty good afterwards.
