Not GP, but as someone who has gotten into running and other sports post-college, yes, I do. I typically look forward to my run each morning - it's the one time of the day I'm not connected to a computer / the internet (I purposefully only bring a watch), and has become almost a form of meditation. I live in a city, so there are a bunch of different routes I can use, and when traveling it's a great way to explore a new area.

Separate from just running, it makes other parts of life more comfortable:

* Walking around is just.. easier - in a weird way, running has mostly solved my knee quirks from when I was younger (when combined with foam rolling and some strength exercises)

* When travelling, I can easily hike 5-15 miles each day with no real issues

* I feel more alert the rest of the day (I like to say that it's my coffee)

* Other sports are easier to get into (skiing, biking, etc) because I have a decent cardio base

Yes. I started very late in life. Never ran before about five years ago. I feel much better.
