The temperature was in the mid 50s (F) during my run. I got tired on the way back but made it. On my way back, I added 10 steps to my running phase; this amounts to about 8 seconds. The tiredness was not from the addition of 10 steps; it was due to the increase of distance before I was used to the lower distance.
It is nice to get to the end of my run and to do a few stretches before entering my car and driving home.
