Day 87 - Long run of 5 miles

NB called at 7 am asking me to get ready by 8. Had asked NB to wake me up only if it stopped raining. Surprisingly, I woke up readily, maybe a little enthususiastically - hint, maybe I have really started to like running. The weather was nice, not windy, not cold. A morning just right for a long run, and it remained so for the duration of the run.
About 10 mins after we started, NB felt a pain in her knee. I wanted her to stop in case it got worse, but she carried on and was ok or said she was ok after some time. The first three miles were good and we ran most of the time, well, more than we usually do. Fourth mile I started getting tired and slowed down. I asked NB to carry on without me at exactly the same place I had told her the same thing last time. Had side splits off and on but enjoyed the run :)
For the first time, I felt real need of water in the fourth mile and for the first time was really tired after the run. Maybe, because it was the first time I had completed 5 miles ;)
