The difference between a training run and a run

This morning I went out for a run, just for fun, leisurely Sunday morning run. My training miles and my "fun" runs are very different:

Training runs include:
1. Intervals
2. Timed miles
3. Mapped routes
4. A training mindset (meaning I push myself harder)

Fun runs are structured very differently:
1. None of the above :). I run 3-5 miles, depending on how I feel. I listen to my body and run a comfortable pace and distance.
2. I enjoy looking around the neighborhood.
3. Take time to think, reflect, meditate and be thankful.

What do you do differently on training runs than "fun" runs?
